| 000656 | CBA/J | Level 2 |
| CBA/J inbred mice are widely used as a general purpose strain. CBA/J strain is the only CBA substrain that carries the Pde6brd1 mutation, which causes blindness by wean age. CBA/J mice are not histocompatible with the CBA/CaJ (Stock No. 000654) substrain (Green and Kaufer, 1965). The CBA/J inbred mouse strain is used to study granulomatous experimental autoimmune thyroiditis (G-EAT), are relatively resistant to diet-induced atherosclerosis (Paigen et al. 1990), and develop a mild hearing loss late in life, with most of the hearing loss occurring in the higher frequencies (Sweet et al. 1988). Renal tubulointerstitial lesions have been observed in this strain at a high frequency (Rudofsky 1978). Some CBA/J mice spontaneously develop exocrine pancreatic insufficiency syndrome (Eppig and Leiter 1977, Leiter et al. 1977). | ||

| Mice that are homozygous for the targeted mutation are viable, fertile, small in size and less active than wildtype controls. Only 10-25% of the expected homozygotes are born. The Donating Investigator reports that breeding homozygous females successfully is uncommon and homozygotes usually succumb before breeding age. No gene product (protein) is detected by Western blot analysis. Homozygotes develop severe polycystic renal disease, with an onset as early as a few weeks of age, and emphysema, with swollen alveoli and breakdown of alveolar walls. Kidney size increases with age. Intestinal and pulmonary inflammation is observed in some homozygotes. Levels of protein polycystin 2 (PC2) is increased in kidney epithelial cells of homozygotes. Histological analysis reveals adipocytes are smaller than wildtype control. | ||
| 016567 | 129S.Cg-Tg(Hoxb7-rtTA*M2)2Cos/J | Repository- Live |
| RS-HTA2 transgenic mice have the homeobox B7 promoter/enhancer sequences driving expression of an optimized form of the reverse tetracycline-controlled transactivator (rtTA*M2) protein. Hemizygotes are viable, fertile, and normal in size. When mated to a second transgenic strain carrying a gene of interest under the regulatory control of a tetracycline-responsive promoter element (tetO), expression of the gene of interest may be regulated by the tetracycline analog, doxycycline (dox). In the presence of dox, transcription of the target gene is induced in cells where rtTA is expressed. When bred to B6;SJL-Tg(tetop-lacZ)2Mam/J mice (Stock No. 002621), adult mice carrying both transgenes, which were maintained on Dox during pre and postnatal life, show strong expression of βgal in the renal collecting duct system, and embryos display strong expression throughout the Wolffian duct, ureteric bud, vas deferens, epididymis .....

| 007853 | 129S/SvEv-Tg(Alb1-Ren)2Unc/CofJ | Repository- Live |
| Mice heterozygous for the RenTgMK transgene are viable and fertile. The RenTgMK transgene contains a liver-specific albumin promoter/enhancer controlling the expression of a synthetic renin gene (engineered to allow efficient cleavage and secretion of the prorenin transgene product by the liver). This, and because the transgene was targeted to the apolipoprotein locus on Chromosome 9, results in active renin secretion from the liver independently of renal or other homeostatic cardiovascular control mechanisms (i.e. genetically clamped). RenTgMK heterozygotes have high ectopic levels of active mouse renin in the liver and elevated plasma levels of prorenin and active renin. Heterozygous mice display significantly elevated blood pressure, enhanced thirst, high urine output, proteinuria, and kidney damage. Because active renin overexpression results in increased circulating levels of angiotensin II (Ang II), heterozygotes also exhibit cardiac hypertrophy and 50% male mortality between 6-8 .....

| 009132 | B6.129P2-P2ry2tm1Bhk/J | Repository- Live |
| Mice that are homozygous for the targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. No gene product (mRNA) is detected by Northern blot analysis of kidney tissue. Intracellular calcium ion levels in lung fibroblasts isolated from homozygotes fail to respond to nucleotide (UTP, ATP, ADP, UDP) challenge. Isolated airway epithelial cells have a loss of or diminished intracellular calcium response to nucleotide challenge. Unlike wild-type macrophages, macrophages derived from these animals fail to respond to extracellular stimulation with UTP. ATP- and adenosine 50[g-thio] triphosphate (ATPgS)-evoked aortic endothelium-dependent relaxation is reduced. Luminal nucleotide stimulated distal colonic ion transport is reduced. Homozygotes are more susceptible to lung infections of Pseudomonas aeruginosa, exhibit impaired neutrophil chemotaxis (loss in gradient sensing and migration distance), and loss of sensitivity to .....

| 013787 | B6.129S1-Abcc6tm1Jfk/J | Repository- Live |
| Mice that are homozygous for this targeted mutation develop patchy, progressive mineralization of the dermis, kidneys, eyes, arteries, heart and subcutaneous tissues, mimicking the human disease symptoms of pseudoxanthoma elasticum. Mineralization of connective tissue capsule surrounding vibrissae is detectable at 5 weeks of age. Mineralization is associated with collagen fibrils and elastic fibers. Oxidative stress, as indicated by lipid peroxidation and protein oxidation, is higher in liver tissue and serum of mutant mice when compared to wildtype controls. Antioxidant diet reduces the oxidative stress levels in knock out mice, but does not prevent ectopic mineralization. The severity of mineralization can be altered by mineral intake as a diet with elevated magnesium levels prevents pathological connective tissue mineralization in mutants. Serum matrix gla protein (MGP) levels are reduced in homozygotes and the protein is under-carboxylated with diminished activity. Fetuin-A .....

| 004525 | B6.129S1-Bcl2l11tm1.1Ast/J | Repository- Live |
| Mice that are homozygous for the targeted mutation are viable, normal in size and do not display any gross physical or behavioral abnormalities. No full length gene product (protein) is immunodetected in spleen cells from homozygous mutant mice. Homozygous mice have lympho-myeloid hyperplasia and reduced platelet number. Lymphocytes are insensitive to certain apoptotic stimuli. Both homozygous and heterozygous mice exhibit progressive systemic autoimmune disease. This mutant mouse strain may be useful in studies of apoptosis, degenerative and autoimmune diseases, including lupus erythematosus and autoimmune kidney disease. | ||
| 010620 | B6.129S1-Notch2tm1Grid/J | Repository- Live |
| Mice that are heterozygous for the targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. Due to alternative splicing, 2 in-frame gene products (mRNA) are detected by RT-PCR analysis of homozygous embryos. The mutant transcripts would produce proteins with one or two EGF repeats deleted. Levels of the mutant transcripts are similar to the wildtype transcript level. This targeted allele is a hypomorph. Homozygotes are neonatal lethal due to developmental defects in the kidney, heart and eye vasculature. Homozygous neonates exhibit hypoplastic kidneys, with vasculature lesions at the cortical surface, and lack mature glomeruli. Bilateral microphthalmia, with retrolenticular hyperplasia, is observed in homozygotes. At age embryonic day 11.5, some homozygous embryos exhibit delayed growth, pericardial effusion and widespread hemorrhaging. Homozygous embryos that survive past embryonic day 11.5 display myocardial hy ..... For more information please see the full phenotype on the strain data sheet | ||
| 009387 | B6.129S1-Osr1tm1Jian/J | Repository- Live |
| The Osr1tm1Jian (Odd1-LacZ) mutation abolishes endogenous gene function and expresses a β-galactosidase fusion protein (fused in-frame with the N-terminal 16 amino acid residues of the endogenous protein). Under control of the upstream promoter/enhancer elements, lacZ expression is directed to the same tissues as the wild-type gene (for example, β-galactosidase expression during embryogenesis is detected at E7.5 in the intermediate mesoderm, is expanded to the gut endoderm, lung bud mesenchyme and myocardial cells by E9.5, and is activated in developing branchial arches and limb buds by E10.5). Almost all (`95%) of homozygous mice die in utero between E11.5-E12.5 from circulation distress; exhibiting malformed atrial septum, dilated atria with hypoplastic venous valves, and blood backflow from the heart into systemic veins. Homozygotes also exhibit complete agenesis of adrenal glands, metanephric kidneys, gonads, and defects in pericard .....

| 009386 | B6.129S1-Osr2tm1Jian/J | Repository- Live |
| The Osr2-lacZ mutation abolishes endogenous gene function and expresses a β-galactosidase fusion protein (fused in-frame with the N-terminal 15 amino acid residues of the endogenous protein). Under control of the upstream promoter/enhancer elements, lacZ expression is directed to the same tissues as the wild-type gene (for example, β-galactosidase expression during embryogenesis is detected by E9.5 in the mesonephric vesicles). Homozygous mice die shortly after birth with open eyelids, bilateral cleft of the secondary palate, and thickened tympanic rings. Heterozygotes are viable and fertile. These Osr2-lacZ mice may be useful as a lacZ reporter for Osr2 expression or as a knockout model for studying developmental biology (craniofacial, limb, and kidney). | ||
| 006133 | B6.129S4-Vdrtm1Mbd/J | Repository- Live |
| Heterozygous mice are phenotypically indistinguishable from wildtype siblings. As originally characterized on a mixed B6;129 genetic background, homozygous mice are viable and fertile with normal survival until approximately 14 months. RNA isolated from the intestine and kidney show a truncated deletion of the second zinc finger coding region followed by a premature termination codon, resulting in the absence of receptor protein. Homozygous mice exhibit an identical phenotype as the human disease hereditary vitamin D-dependent rickets type II (HVDDR). As early as 21 days of age, mutant mice demonstrate hypocalcemia, hypophosphatemia, hyperparathyroidism, increased serum parathyroid hormone, abnormal blood mineral levels, and growth retardation. In addition, renin and plasma angiotensin II levels are increased. Homozygous mice are hypertensive and exhibit cardiachypertrophy. At 4 weeks of age, homozygous mice exhibit perioral and periorbital alopecia that progresses over the entire bod ..... For more information please see the full phenotype on the strain data sheet | ||
| 008101 | B6.129S6(FVB)-Ptgs2tm1.1Fun/J | Repository- Live |
| Mice that are homozygous for the targeted mutation are viable, normal in size and do not display any gross physical or behavioral abnormalities. Female homozygotes are not fertile. The protein gene product does not have cyclooxygenase activity while the peroxidase activity is normal as measured by LPS induction of macrophages derived from mutant mice. Mutant mice are more sensitive to collagen treatment resulting in reduction of platelet numbers (indicating enhanced thrombogenesis) and exhibit a higher frequency of sudden death due to thromboxane receptor agonist treatment. No prolonged bleeding time from LPS administration is observed. Prostaglandin E metabolite levels are diminished in urine. Three month old mutant mice have elevated systolic blood pressure (measured by the tail cuff method). Homozygotes exhibit undersize, pale kidneys with atrophic cortices, interstitial inflammation, hypoplastic glomeruli and glomerulosclerosis.
This mutant mouse strain may be useful in studies of ..... For more information please see the full phenotype on the strain data sheet | ||

| Mills 1999 Nature 398:708 describes the homozygous phenotype on a mixed B6-Tyrc-Brd;129S7(129S5) background. Further, they not distinguish between the two targeted alleles (pTV6H(90)-generated p63Brdm1 [Trp63tm1Brd] or pTV12E(60)-generated p63Brdm2 [Trp63tm2Brd]) as both "produced an identical phenotype." Homozygous mice are born alive, but die several hours after birth. No transcripts have been detected in homozygotes. They have striking developmental defects, exhibiting truncated forelimbs, absent hindlimbs, and transparent skin with a complete lack of hair follicles. Both the gross and histological appearance of internal organs is normal. Functional permeability of the skin is dramatically increased; homozygous mice lose thirty times more water than normal littermates. It is presumed that death occurs from dehydration. Heterozygous mice are viable, fertile, and do not exhibit any overt developm ..... For more information please see the full phenotype on the strain data sheet | ||
| 000305 | B6.Cg-Fbn1Tsk +/+ Pldnpa/J | Repository- Live |
| Mice homozygous for the pallid spontaneous mutation Pldnpa and nonagouti (a) have pink eyes and a light, yellow-brown coat. The Pldnpa/Pldnpa mice have a slightly lighter coat than strains that are homozygous for the pink-eyed dilution allele (Oca2p/Oca2p). Viability of homozygous mutant mice is slightly reduced. Some homozygotes have slightly abnormal behavior, with abnormal postural responses and head tilting due to the absence of otoliths in the sacculus and utriculus in many but not all mutant mice. The effect of pallid on behavior and otolith morphology appears to be a result of manganese deficiency. Homozygotes display defective mucopolysaccharide synthesis in the otolith matrix and a slower rate of transport of manganese, L-dopa, and L-tryptophane in the brain. Homozygotes have elevated basal and testosterone-induced levels of the kidney lysosomal enzymes b-glucuronidase, b-galactosi .....

| 000528 | B6.Cg-PhexHyp/J | Repository- Live |
| Hypophosphatemia (PhexHyp) is an X-linked semidominant mutation that causes defects in phospate metabolism. It is allelic with the gyro mutation (PhexGy) but hypophosphatemia mutant mice do not circle. Hemizygous males and heterozygous females can be recognized at 20 to 30 days of age by their shortened hindlimbs and tail. They have reduced body size which persists throughout life, and skeletal changes resembling rickets. Hemizygous males are more affected than heterozygous females. Viability is normal in both sexes, but heterozygous females show better fertility than hemizygous males. | ||
| 016209 | B6;129-Lrrk2tm2.1Shn/J | Repository- Live |
| Mice homozygous for the LRRK2 KO1 mutation are viable and fertile, with the promoter and exon 1 of the Lrrk2 (leucine-rich repeat kinase 2) gene deleted. No mRNA or protein expression from the targeted allele is observed in brain tissues, however and truncated mRNA signal is observed in kidney tissue. Homozygous mice do not exhibit neurodegeneration or neuropathological changes in the brain. In the kidneys, a tissue where LRRK2 is normally expressed at ~6-fold greater levels than brain, homozygous loss of LRRK2 results in renal atrophy by 20 months of age. This is accompanied by significant (~60-fold) age-dependent accumulation of aggregated α-synuclein and ubiquitinated proteins in the kidney. Specifically, homozygous KO kidneys show widely distributed cytosolic α-synuclein-immunoreactive granular aggregates (some amy also contain phospho-Ser-129 α-synuclein) or inclusions in boxy cells of renal tubules in the cortical area by 20 months of age. Other kidney ..... For more information please see the full phenotype on the strain data sheet | ||

| 012463 | B6;129S4-Foxd1tm1(GFP/cre)Amc/J | Repository- Live |
| Heterozygous mice are viable and fertile, normal in size and do not display any gross physical or behavioral abnormalities. The DI states that the strain is homozygous lethal. The FoxD1GC allele expresses an eGFPCre fusion protein (EGFP and cre fusion protein) from the Foxd1 promoter/enhancer elements. When Foxd1 is induced, EGFP immunofluorescence is observed during kidney development in metanephric mesenchyme in cells fated to become stromal cells of the kidney. When FoxD1GC mice are bred with mice containing loxP-flanked sequence, Cre-mediated recombination will result in deletion of the floxed sequences in the Foxd1-expressing cells of the offspring. These mice may be useful for studying therapeutic strategies directly targeting pericyte differentiation in vivo and may productively impact fibrotic kidney disease. | ||

| Heterozygous mice are viable and fertile, normal in size and do not display any gross physical or behavioral abnormalities. The DI states that the strain is homozygous lethal. The Foxd1GCE allele expresses an eGFPCreERT2 fusion protein (EGFP and creERT2 fusion protein) from the Foxd1 promoter/enhancer elements. Foxd1 is induced, and EGFP immunofluorescence is observed, during kidney development in metanephric mesenchyme in cells fated to become stromal cells of the kidney. Cre-ERT2 fusion gene activity is inducible; observed in the same cells only following tamoxifen administration. When Foxd1GCE mice are bred with mice containing loxP-flanked sequence, tamoxifen-inducible, Cre-mediated recombination will result in deletion of the floxed sequences in the FoxD1-expressing cells of the offspring.

| Mice homozygous for the adult nephrogenic diabetes insipidus mutation can often be initially detected by a slight reduction in body size by wean age. By 4 to 6 weeks of age polyuria, polydipsia, and low urine osmolality can be detected and none of these phenotypes are responsive to DDAVP. Histology reveals highly abnormal renal tubules. Homozygotes breed but should not be relied upon to breed for as long as heterozygotes or wild-type BALB/cByJ mice because progressive hydronephrosis develops. | ||
| 008340 | BKS.Cg-Leprdb Nos3tm1Unc/RhrsJ | Repository- Live |
| These double mutant mice harbor both the Leprdb spontaneous mutation and the Nos3 (eNOS) targeted mutation and are congenic on C57BLKS/J genetic background. Mice homozygous for both mutations (called eNOS-/- C57BLKS/J db/db, eNOS-/- db/db, or db/db/eNOS-/- double mutant mice) are viable with development of type II diabetes and diabetic nephropathy. The eNOS-/- C57BLKS/J db/db mice develop type II diabetes with significant obesity and hypertension: while both mutations are associated with insulin resistance, the mutated leptin receptor in db/db mice chiefly accounts for the observed hyperglycemia and defective leptin signaling (leading to persistent hyperphagia and obesity), and the eNOS-deficiency accounts for the moderate systemic hypertension. In addition, eNOS-/- C57BLKS/J db/db mice exhibit rapid onset and progression of pathologic ..... For more information please see the full phenotype on the strain data sheet | ||

| Mice homozygous for the beige-J spontaneous mutation (Lystbg-J) are identical to the original beige mutation (Lystbg). The phenotype closely resembles Chediak-Higashi disease in man and similar conditions in mink and cattle. Abnormal giant lysosomal granules occur in all tissues with granule-containing cells, including granulocytes, lymphocytes, cells of the liver, kidney, central nervous system, pancreas, and thyroid, and the ducts of most glands; in type II pneumocytes; in mast cells; and in retinal pigment epithelium. Granulocytes from beige homozygous mutant mice mice show defective chemotaxis and reduced bactericidal activity. Beige mice are more susceptible than controls to pneumonitis and to various viral, bacterial, and parasitic infections. Natural killer (NK) cells from beige mice exhibit decreased endogenous cytotoxic activity. Beige mice also have a defective cytotoxic T-cell and cytotoxic antibody response to allogeneic tumor cells.

| In the BALB.LDLR-/- strain, a neomycin (neo) selection cassette is inserted in exon 4 of the low density lipoprotein receptor (Ldlr) gene, abolishing endogenous gene function. Homozygous mice are viable, fertile, appear normal in size, and do not display any gross physical or behavioral abnormalities. On a 4% diet, BALB.LDLR-/- mice have increased cholesterol (~200 mg/dl), increased triglycerides (~170mg/dl), and increased blood glucose (122 mg/dl) as compared with wildtype (WT). When moved onto a 21% fat diet these mice have cholesterol levels of 572 mg/dl, triglyceride levels of 180mg/dl, and blood glucose levels of 141 mg/dl. They exhibit renal injury, tubulointerstitial injury, and an increase in interstitial macrophages, and an increase in blood urea nitrogen when challenged with hyperlipidemia and hyperglycemia. When injected with Streptozotocin these mice also exhibit atherosclerotic lesions, aortic sinus lesions, and aortic fatty streak lesions .....

| DBA/2J mice heterozygous for the Akita spontaneous mutation are viable and fertile. The donating investigator reports that the symptoms in heterozygous mutant mice are more severe and progressive in the males than in the females and include hyperglycemia, hypoinsulinemia, polydipsia, and polyuria, beginning at approximately 3-4 weeks of age. Obesity and insulitis do not accompany diabetes. Litter sizes range from 2-8 pups. Heterozygous Akita males develop albuminuria at two months of age. The albuminuria is progressive such that by 6 months of age albumin/creatine levels are approximately 600ug/mg. Additionally, it has been reported that DBA/2J heterozygous mutant mice develop diabetic nephropathy.
Although not studied in the DBA/2J heterozygotes, C57BL/6 heterozygous mutant mice exhibit gait disturbance and decreased sensory nerve conduction velocity, but do not exhibit learning or memory deficits (Choeiri C et al., 2005). Progressive retinal abnormalities begin as early as ..... | ||

| Mice that are heterozygous for the Nephrin KO/GFP knock-in mutation are viable and fertile. Homozygous mice die within a few days after birth with massive glomerular vascular leak and an absence of glomerular epithelial slit diaphragms. No gene product is detected by Western blot of kidney tissue of homozygotes. Green fluorescent protein (GFP) is detected in glomeruli of homozygotes and heterozygotes. Newborn homozygotes show extensive proteinuria, while heterozygotes show none. These Nephrin KO/GFP knock-in mice may be useful in studying nephrotic syndrome or any of the diseases where plasma ultrafiltration is affected. | ||

| Homozygous mice die between embryonic day (E)13.5 and birth with defects of heart, kidney, gonads, and multiple other organs. Heterozygous (Wt1GFPCre/+) mice are viable and fertile. The Wt1GFPCre "knock-in" allele both abolishes Wt1 gene function and expresses an enhanced green fluorescent protein-Cre recombinase fusion protein (EGFPCre) from the Wt1 promoter/enhancer elements. In heart from heterozygous mice, EGFPCre expression is directed to proepicardium and epicardium from E9.5 to E15.5, and is not found in the myocardium. When bred to mice containing loxP-flanked sequences, the resulting offspring will have Cre-mediated deletion of the floxed sequences in the Wt1-expressing cells (and their descendants). As Wt1 is expressed in the developing genitourinary system and in the mesothelia overlying most visceral organs, these mutant mice may be useful as fluorescent/Cre-lox tools for lineage-tracing/marking Wt1-expressin .....

| Homozygous mice die between embryonic day (E)13.5 and birth with defects of heart, kidney, gonads, and multiple other organs. Heterozygous (Wt1CreERT2/+) mice are viable and fertile. The Wt1CreERT2 "knock-in" allele both abolishes Wt1 gene function and has expression of the CreERT2 fusion protein (CreERT2) under control of the Wt1 promoter/enhancer elements. In heart from heterozygous mice, CreERT2 expression is directed to proepicardium and epicardium from E9.5 to E15.5, and is not found in the myocardium. CreERT2 fusion gene activity is inducible; observed following tamoxifen administration. As such, when Wt1CreERT2 mice are bred with mice containing loxP-flanked sequence, tamoxifen-inducible Cre-mediated recombination will result in deletion of the floxed sequences in the Wt1-expressing cells of the offspring.

This combination of abnormalities is characteristic of a human hereditary disease, Hermansky-Pudlak syndrome. Pearl mice also exhibit reduced sensitivity in the dark-adapted state, altered somatostatin binding to the retina, and an increased rate of renal apoptosis, making them a potential model for human congenital stationary night blindness. | ||
| 006616 | 129(B6)-Ccnitm1Jro/J | Cryopreserved - Ready for recovery |
| Mice homozygous for this targeted mutation are viable and fertile and do not display any gross physical or behavioral abnormalities. No protein product from the targeted gene is detected in the tissues tested. Distinct lacZ staining is seen in the glomerulus of podocytes in the kidney. Weaker and variable expression of lacZ is seen in tubular cells. Increased susceptibility to apoptosis both in vitro and in vivo is observed. Following induction of experimental glomerulonephritis, podocyte apoptosis was increased 4-fold in homozygotes, which is associated with dramatically decreased renal function. This mutant mouse strain represents a model that may be useful in studies of apoptosis, renal impairment and glomerulosclerosis. | ||
| 006239 | 129-Wnt11tm1Amc/J | Cryopreserved - Ready for recovery |
| Mice heterozygous for this targeted mutation are viable and fertile with normal kidney size and histology. Homozygotes exhibit some embryonic lethality and will die by 2 days post partem. While the cause of death is unclear, these neonates have kidney hypoplasia and reduction of glomeruli. RT-PCR analysis of kidney RNA shows the expected truncated transcript. Homozygotes exhibit ureteric branching morphogenesis defects between embryonic day 11.5-12.5 (T-stage) associated with a reduction in mesenchymal Gdnf expression. These Wnt11 mutant mice may be useful in studies of kidney development, including ureteric bud branching morphogenesis, and Wnt superfamily embryogenesis. | ||

| Mice homozygous for this "Cyp 4a14" mutant allele are viable and fertile. Homozygous deficiency of the targeted gene leads to spontaneous hypertension (more severe in males) that is androgen-sensitive. Homozygotes also exhibit other interrelated metabolic and regulatory effects; increased renal vascular resistance, impaired renal hemodynamics, elevated plasma androgens (5α-dihydrotestosterone (DHT) and testosterone), upregulated Cyp4a12 gene expression, and increased formation of prohypertensive 20-HETE. These "Cyp 4a14" mutant mice may be useful studying kidney function and metabolism, cardiovascular physiology, hypertension, and the relationships between blood pressure, sex hormones, and p450 ω-hydroxylases. | ||

| Mice homozygous for this mutant allele have reduced size and weight gains after birth and do not survive past 8 weeks of age. Homozygotes occur at a lower than Mendelian ratio (19%) from heterozygote X heterozygote crosses. No gene product is detected in homozygous embryos aged ED9.5-12.5 or in adult gonad. Beta-galactosidase staining pattern mimics the endogenous gene expression pattern in adult intestinal epithelial cells. Homozygous embryos E11.5 to E18.5 exhibit hemorrhages and microaneurisms. Vascular defects persist into adulthood. At 6 weeks of age, mutant mice are anemic (low hemoglobin concentration, reduced red blood cell count, low hematocrit). Mutants exhibit polychromasia (abnormally high number of immature blood cells), kidney defects (blood urea nitrogen level abnormally high, kidney size smaller than wildtype, swollen blood filled glomeruli, reduced number of vascular smooth muscle cells) and abnormalities in palate bone fusion. Homozygotes are infertile. Heterozygote ..... For more information please see the full phenotype on the strain data sheet | ||

| Homozygous targeted mutant animals develop obesity that increases with age (cause unknown). They have phenotypes associated with selective cilia dysfunction, including retinopathy, renal cysts, and a deficit in olfaction. Retinal degeneration is characterized by a mislocalization of rhodopsin followed by photoreceptor apoptosis. Male sperm do not develop flagella, causing infertility. Heterozygous crosses produce fewer homozygotes than predicted by Mendelian ratios. Mice also exhibit a defect in social function. | ||

Homozygous mice die around 16-24 hours after birth, exhibiting abnormalities in kidney/urinary (renal agenesis/hypodysplasia) and peripheral nervous system development (including sympathetic, parasympathetic, and enteric ganglia), as well as abnormal enteric neural crest cell migration. Because homozygous mice lack enteric ganglia from the hindgut, these mice are also a model of Hirschsprung's Disease. | ||
| 003082 | 129S1/SvImJ-Bcl2tm1Mpin/J | Cryopreserved - Ready for recovery |
| Heterozygous mice exhibit expression of beta-galactosidase in populations of large sensory neurons. Mice homozygous for the Bcl2tm1Mpin targeted mutation do not produce either the a or b form of the Bcl2 protein. Bcl2 is a major regulator of programmed cell death, a critical process in shaping the developing nervous system. The absence of the Bcl2 does not significantly influence the development of motor neurons before or during the main period of physiological cell death. Rather, Bcl2 exerts its influence beyond this period, subsequent to the phase where the majority of neuronal loss normally takes place. Polycystic kidney disease is less severe in this strain compared to the Bcl2tm1Sjk targeted mutation (Stock No. 002265). | ||
| 000277 | ATEB/LeJ | Cryopreserved - Ready for recovery |
| Mice homozygous for the atrichosis spontaneous mutation (at) are characterized by sparsely distributed hair, especially on the trunk. The amount of hair varies, but affected mice can be easily recognized at 8 to 10 days old. Both sexes are sterile and have very small gonads with few germ cells. There is a great deficiency of primary spermatogonia in the testes. A quantitative study of maturation of ovarian oocytes showed that the proportion of resident oocytes recruited into the first wave of growth was much higher than in phenotypically normal heterozygous controls (J.J. Eppig, personal communication). This strain is also segregating for the eye blebs spontaneous mutation (Grip1eb). | ||
| 000477 | B10.PA-Pldnpa H3e at/SnJ | Cryopreserved - Ready for recovery |
| This minor histocompatibility 3 (H3e) congenic strain is also carrying the closely linked pallid mutation (Pldnpa) as well as the black and tan allele of nonagouti also residing on Chromosome 2. Histocompatibility 3 is one of several loci isolated and identified by Dr. George Snell and co-workers. Histocompatibility gene differences were identified by generating congenic resistant strains and testing for resistance to transplantable tumors. Homozygous pallid mice have pink eyes, a diluted coat color and their viability is slightly reduced. Some homozygotes have slightly abnormal behavior, with abnormal postural responses and head tilting due to the absence of otoliths in the sacculus and utriculus in many but not all mutant mice. The effect of pallid on behavior and otolith morphology appears to be a result of manganese deficiency. Homozygotes display defective mucopolysaccharide synthesis in the otolith matrix and a slower rate of transport of manga .....

| 013168 | B6.129-Ahi1tm1Jgg/J | Cryopreserved - Ready for recovery |
| Homozygous Ahi1 (Abelson helper integration site 1) targeted mutation mice, completely lacking protein expression, are severely runted and frequently die during the neonatal period. Approximately 80% reportedly do not survive to adulthood. Surviving homozygotes exhibit retinal photoreceptor degeneration and also develop a mild, late-onset cystic kidney phenotype. By 5 months of age, the kidneys of homozygotes are smaller compared to littermate controls and show the characteristic histological triad of nephronophthisis: 1) tubular basement membrane abnormalities, including thickening and disintegration with tubular collapse; 2) interstitial cell infiltrate and fibrosis; 3) delayed appearance (1 year) of multiple microcysts and tubular dilation. This strain may be useful as a model of Joubert syndrome. | ||
| 002831 | B6.129-Ahrtm1Bra/J | Cryopreserved - Ready for recovery |
| Mice homozygous for the targeted mutation are viable. Homozygotes do not respond to aryl-hydrocarbon receptor agonists. They show reduced liver weight (25% decrease) delayed extramedullary hematopoiesis, and transient hepatic microvesicular steatosis. | ||
| 010727 | B6.129-Bbs2tm1Vcs/J | Cryopreserved - Ready for recovery |
| Homozygous targeted mutant animals develop obesity that increases with age (cause unknown). They have phenotypes associated with selective cilia dysfunction, including retinopathy, renal cysts, and a deficit in olfaction. Retinal degeneration is characterized by a mislocalization of rhodopsin followed by photoreceptor apoptosis. Male sperm do not develop flagella, causing infertility. Heterozygous crosses produce fewer homozygotes than predicted by Mendelian ratios. Mice also exhibit a defect in social function. This strain may be useful as a model for Bardet-Biedl syndrome. | ||

| Mice homozygous for the targeted mutation and heterozygous for the Ins2Akita spontaneous mutation are viable and fertile. Similar to mice only heterozygous for the Ins2Akita mutation, the double mutant mice are severely diabetic: their body weights are 70% of wildtype, they consume over 3-fold the normal amount of food, and their urinary output is approximately 20-fold more than that of wildtype mice. Double mutant mice have markedly enlarged kidneys. Urinary albumin excretion in double mutants is almost 4-fold that of either single mutant, and double mutants experience more severe nephropathy than mice that are heterozygous for the Akita mutation alone. Megsin and nephrin expression is markedly increased in double mutant mice when compared to wildtype or to mice with either single mutation alone. By 12 months of age, double mutant mice experience hair loss due to a reduction in hair follicle numbers and thinning of the dermis. Double mutants .....

| 002681 | B6.129P2-Agttm1Unc/J | Cryopreserved - Ready for recovery |
| Newborn homozygotes for the targeted disruption of Agt have no obvious pathological defects although only a few survive to adulthood. There are pathological changes in adult kidney and blood vessels. The effect of gene copy number was examined using these mice and C57BL/6J-TgH(Agtdup)1Unc (002690). Plasma angiotensinogen levels increase progressively, although not linearly, from zero in zero-copy (Agttm1Unc/Agttm1Unc) mice to 145% of normal in four-copy (Agtdup/Agtdup) mice. Mice of all genotypes are normal at birth, but most zero-copy animals show pathological changes as adults, the kidneys are normal in the other genotypes. The blood pressures of the one-copy through four-copy animals show significant and almost linear increases of approximately 8mmHg per gene copy despite their normal compensatory mechanisms being intact. | ||
| 010949 | B6.129P2-Grem1tm1Rmh/J | Cryopreserved - Ready for recovery |
| Mice that are homozygous for the targeted mutation lack kidneys and die within 48 hours of birth. These mice exhibit a single bone in both the forelimb and hindlimb zeuogopod, missing digits and abnormal maintenance of interdigital tissue. Beta galactosidase expression in the embryonic limbs, somites and flank is consistent with the expression of gremlin 1. This mutant mouse strain may be useful in studies of limb patterning and kidney development.
In an attempt to offer alleles on well-characterized or multiple genetic backgrounds, alleles are frequently moved to a genetic background different from that on which an allele was first characterized. It should be noted that the phenotype could vary from that originally described. We will modify the strain description if necessary as published results become available. | ||

| Mice homozygous for the Bmp4tm1Blh targeted mutation mutation die early in embryogenesis. Fifteen to twenty percent of heterozygous mice show developmental defects including polydactyly, craniofacial defects, and cystic kidneys. Heterozygotes have also been reported to show eye abnormalities. | ||
| 004802 | B6.129S2-Slc34a1tm1Hten/J | Cryopreserved - Ready for recovery |
| Mice that are homozygous for the targeted mutation are viable and fertile, and do not display any gross physical or behavioral abnormalities. No gene product (mRNA or protein) is detected by Northern blot analysis of bone, kidney, liver or lung, or by Western blot analysis of kidney. Homozygotes are smaller in size and have reduced weight compared to wildtype littermates. Secondary ossification defects revealed at weaning are followed by compensatory bone development. Mutant mice exhibit increased urinary excretion of inorganic phosphate and calcium, diet dependent hypercalciuria and hypercalcemia, as well as decreased serum parathyroid hormone levels, increased serum alkaline phosphatase activity, and elevated serum 1,25-dihyudroxyvitamin D. Homozygous mice do not respond to dietary challenges of low inorganic phosphate or parathyroid hormone content. Calcium and inorganic phosphate containing renal stones, nephrocalcinosis, are found in homozygotes at all ages. This mutant mouse stra .....

| 002719 | B6.129S4-Wt1tm1Jae/J | Cryopreserved - Ready for recovery |
| Mice homozygous for the Wt1tm1Jae targeted mutation die between embryonic days 13 and 15. They fail to develop a kidney or gonads. The hearts of homozygous mutant mice also fail to develop properly. Hearts are smaller than wildtype controls and possess a rounded apex. The right ventricular wall is thin and the left ventricle is reduced in size. There appears to be normal development of the aortic, pulmonary, mitral and tricuspid valves. Development of the diaphragm is also incomplete resulting in incomplete separation of the thoracic and abdominal cavities. Homozygous mutant lungs are also markedly smaller than wild type lungs. Heterozygous mice appear normal and show no tumor development (mice followed until 10 months of age). | ||
| 009679 | B6.129S6-Pkhd1tm1Cjwa/J | Cryopreserved - Ready for recovery |
| Mice that are homozygous for the targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. A mutant gene product (mRNA), that skips exon 2 using the splice donor of exon 1 and the splice acceptor of exon 3, is detected by RT-PCR of kidney and liver tissue. By 9 months of age, homozygotes develop age progressive fibrocystic liver disease and cystic dilation of the kidney. Some homozygotes develop enlarged cystic pancreas. Histological analysis of females 3 months of age reveals dilated proximal convoluted tubules with attenuated brush border. This mutant mouse strain may be useful in studies of Polycystic Kidney Disease. | ||
| 003336 | B6.129S7-Cdkn1ctm1Sje/J | Cryopreserved - Ready for recovery |
| Mice lacking the Cdkn1c gene have altered cell proliferation and differentiation, leading to abdominal muscle defects; cleft palate; endochrondral bone ossification defects with incomplete differentiation of hypertrophic chondrocytes; renal medullary dysplasia; adrenal cortical hyperplasia and cytomegaly; lens cell hyperproliferation and apoptosis. The targeted gene is imprinted. The phenotype differs depending on whether the targeted allele is transmitted from the dam or the sire; maternal inheritance of the null allele is lethal. This is a model for the human Beckwith-Wiedemann syndrome. | ||
| 005643 | B6.129X-Gusbtm1Sly/J | Cryopreserved - Ready for recovery |
| Homozygous mice are viable but have reduced neonatal survival. Homozygotes are infertile, but fertility can be restored with enzyme replacement therapy. No residual enzyme activity is observed. Homozygous mice are indistinguishable from heterozygous and wild type mice at birth, but show distinct growth retardation, shortened extremities, and facial dysmorphism observable at wean and increasing in severity with age. Long bones of the lower extremities are shortened, broad, and sclerotic. Compared to wild-type, this model has increased urinary glycosaminoglycan and secondary elevation of other lysosomal storage enzymes. Further, homozygous mice show abundant lysosomal storage in liver, kidney, leptomeningeal cells, cornea, spleen, neurons, and retinal pigment epithelium. The phenotype exhibited by this mutant mouse strain is more severe than that observed in a similarly constructed mutant (Stock No. 005644) which bears a L175F point .....

| Homozygous mice are viable but infertile. Fertility can be restored with enzyme replacement therapy. Less than 1% residual enzyme activity is observed. Homozygous mice are indistinguishable from wild type mice at birth, but show distinct growth retardation, shortened extremities, and facial dysmorphism observable at three months with a moderate increase in severity with age. Long bones of the lower extremities are shortened, broad, and sclerotic. Compared to wild-type, this model has increased urinary glycosaminoglycan and secondary elevation of other lysosomal storage enzymes. Further, homozygous mice show abundant lysosomal storage in liver, kidney, leptomeningeal cells, cornea, and retinal pigment epithelium.

| 008907 | B6.129X1-Cd2aptm1Shaw/J | Cryopreserved - Ready for recovery |
| Homozygous targeted mutant mice begin to show growth retardation at about 3 weeks of age, and die at approximately 6 weeks. Cardiac hypertrophy, splenic and thymic atrophy, and ascites may be found upon postmortem examination. Proteinuria can be detected as early as 2 weeks of age, indicating kidney dysfunction. The predominant kidney pathology involves glomeruli which become sclerotic by 4 weeks. CD2AP protein is not detected in the thymus, kidney, liver or spleen of homozygous targeted animals. Naive and cultured T cells show increased sensitivity to antigen, increased proliferation, increased number of cell divisions and increased apoptosis compared to wild type cells. Heterozygotes show increased susceptibility to glomerular injury by nephrotoxic antibodies or immune complexes. | ||
| 009365 | B6.129X1-Mark2tm1Hpw/J | Cryopreserved - Ready for recovery |
| Homozygous targeted mice show and increased metabolic rate, decreased adiposity, resistance to high fat diet-induced weight gain, and insulin hypersensitivity. Western blot analysis demonstrates that expression is eliminated in brain, spleen, kidney and liver, lymph nodes, thymus, white and brown adipose tissues, large and small intestines, stomach. Homozygous pups are born slightly below predicted Mendelian ratios and show both embryonic and postnatal growth retardation as well as increased mortality as compared to wildtype animals. The age of death can range from 3 weeks to several months. Approximately 85% of homozygotes exhibit some combination of immunological disorders between the ages of 5 and 12 months. B and T cell development is normal, but CD4+ T cells lacking this protein exhibit a marked upregulation of the memory marker CD44 and produce more gamma interferon and interleukin 4 on stimulation through the T cell receptor in vitro. B cell responses to T ..... For more information please see the full phenotype on the strain data sheet | ||

| Homozygotes have spherocytic hemolytic anemia and neonatal jaundice. Erythrocytes have diminished biconcavity, a smaller than normal diameter, increased density, an appearance of exovesiculation, and a short lifespan. At birth homozygotes are very pale then become yellow during the first few hours of life and die generally within a day of being born. Although it is rare for a spherocytosis homozygote to survive beyond one day of birth on the C57BL/6J or WB/Re (stock #000454) congenic background, homozygotes on the (C57BL/6J x WB/Re)F1 background are much more robust and the majority survive to adulthood. Those that make it to wean age are expected to have a reasonable lifespan, sometimes living as long as a year. Thus, most studies of this mutation in the adult have been done on the (C57BL/6J x WB/Re)F1 background. These homozygotes display diminished hematocrit, decreased red blood cell count, very elevated red blood cell protoporphyrin levels, increased erythropoiesis, reticulo .....

| Mice homozygous for the beige spontaneous mutation (Lystbg) are characterized by a condition that closely resembles Chediak-Higashi disease in man and similar conditions in mink and cattle. Abnormal giant lysosomal granules occur in all tissues with granule-containing cells, including granulocytes, lymphocytes, cells of the liver, kidney, central nervous system, pancreas, and thyroid, and the ducts of most glands; in type II pneumocytes; in mast cells; and in retinal pigment epithelium. Granulocytes from beige homozygous mutant mice mice show defective chemotaxis and reduced bactericidal activity. Beige mice are more susceptible than controls to pneumonitis and to various viral, bacterial, and parasitic infections. Natural killer (NK) cells from beige mice exhibit decreased endogenous cytotoxic activity. Beige mice also have a defective cytotoxic T-cell and cytotoxic antibody response to allogeneic tumor cells. Syngeneic tumor cells grow better in beige mice than in l ..... For more information please see the full phenotype on the strain data sheet | ||

| Ap3b1 encodes the beta-3A subunit of the adaptor protein complex 3 (AP-3). Mice that are homozygous for the targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. No Ap3b1 mRNA is detected by Northern blot analysis of spleen and kidney tissue, and beta-3A immunoreactivity is absent in monocytes from homozygous mice. In brain tissue from homozygous mutants, expression levels of the AP-3 beta-3B (beta-NAP), mu-3 and sigma-3 subunit proteins are normal, but expression of the delta-3 subunit protein is reduced. In kidney, no sigma-3 protein is detected, and mu-3 and delta-3 subunit proteins levels are greatly reduced.
Homozygotes have a diluted coat color (light gray), which is lighter than the coats of homozygotes carrying the allelic pearl (Ap3b1pe) spontaneous mutation. Cultured melanocytes from homozygous mutant mice have very few pigment granules. Lysosomal-associated membrane ..... | ||

| Heterozygous females and hemizygous males for the targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. Immunofluorescence analysis of kidney tissue from mutant male mice does not detect gene product (protein), but in kidney from mutant female mice a mosaic pattern of gene product (protein) is detected (due to X-inactivation). RNase protection assay analysis of kidney tissue from mutant male mice detects a significantly lower level than wildtype. Hemizygous male and heterozygous female mice develop progressive kidney disease. By 7 weeks of age, 97% of mutant male mice and 78% of heterozygous female mice exhibit proteinuria. Histological analysis of kidneys from mutant male mice at 4 weeks of age reveals thickened capillary walls and mesangial hypercellularity. The pathology progresses to interstitial inflammation, glomerular abnormalities, and focal sclerosis. Electron microscopic examination of glomerular basement memb .....

| 006407 | B6.Cg-Gusbmps/BrkJ | Cryopreserved - Ready for recovery |
| Mice homozygous for the "mps" (mucopolysaccharidosis type VII or MPS VII) mutation are devoid of expression of the lysosomal enzyme beta glucuronidase. Homozygous animals are viable, but females have a deficiency in lactation. Skeletal and connective tissue anomalies in both males and females are believed to prevent successful breeding. As this mutation is recessive, heterozygous mice are phenotypically similar to wildtype. Homozygotes exhibit short and thickened long bones (smaller than heterozygous or wildtype littermates), "pug type" appearance of the nose, hepatomegaly, splenomegaly, corneal clouding, and deafness. These mice have the H2b haplotype typical of inbred C57BL/6 mice. MPS VII mice are a model of the beta glucuronidase enzyme deficiency in humans called Sly Disease. They may be useful in developing new therapies (enzyme replacement, cell transplantation, gene therapy) broadly applicable to other lysosomal storage diseases. | ||

| Kit mice possess pleiotropic defects in pigment-forming cells, germ cells, RBC's and mast cells. In addition, they exhibit impaired resistance to parasitic infection and an intrinsic progenitor cell defect. KitW-v homozygotes resemble KitW homozygotes in color, anemia, and germ cells, but many of them survive to maturity. The lack of germ cells in mutant mice leads to the development of some ovarian tumors (mesotheliomas and granulosa cell), associated with an overproduction of pituitary gonadotropic hormone. Heterozygous lx mice show preaxial polydactyly (including hyperphalangy of the first digit) of the hindfeet. Homozygotes show preaxial polydactyly or oligodactyly of the hindfeet, reduction of the tibia, loss of part of the femur and pubis, decrease in number of presacral vertebrae, and anomalies of the urogenital system including horseshoe kidney, hydronephrosis, and hydroureter.

| Mice homozygous for the leaner spontaneous mutation (Cacna1atg-la) begin to show ataxia, stiffness, and retarded motor activity by 8 to 10 days of age. Many homozygous mutant mice die by weaning age, but some survive, and females may even breed. Homozygous mutant adults are characterized by instability of the trunk and hypertonia of the trunk and limb muscles. Seizures have not been observed. The cerebellum is reduced in size, particularly in the anterior region. There is loss of granule cells beginning at 10 days of age and loss of Purkinje and Golgi cells beginning after 1 month. Leaner/tottering heterozygotes (Cacna1atg-la/Cacna1atg) show ataxia, stiffness, and retarded motor activity at 15 to 17 days of age. Within a few days, they develop a wobbly gait and intermittent focal seizures which continue throughout life. The cerebellum shows shrinkage and degenerative changes of the Purkinje cells. | ||
| 000024 | B6.Cg-Pldnpa/J | Cryopreserved - Ready for recovery |
| Mice homozygous for the pallid spontaneous mutation pa and nonagouti (a) are pink-eyed and have a light, yellow-brown coat. The coat is a little lighter than that of pink-eyed dilution homozygotes (p/p). Viability of homozygote mutant mice is slightly reduced. Some homoygotes have slightly abnormal behavior, with abnormal postural responses and head tilting due to the absence of otoliths in the sacculus and utriculus in many but not all mutant mice. The effect of pallid on behavior and otolith morphology appears to be a result of manganese deficiency. Homozygotes display defective mucopolysaccharide synthesis in the otolith matrix and a slower rate of transport of manganese, L-dopa, and L-tryptophane in the brain. Homozygotes have elevated basal and testosterone-induced levels of the kidney lysosomal enzymes b-glucuronidase, b-galactosidase, and a-mannosidase, accompanied by lowered enzyme excretion in the urine. Pallid mice have a deficiency in serum a1-antitrypsi ..... For more information please see the full phenotype on the strain data sheet | ||
| 006210 | B6.Cg-Spna1ihj/LlpJ | Cryopreserved - Ready for recovery |
| Although normal in appearance at birth, homozygotes are smaller than normal by 2 days of age and there is a high rate of neonatal death and death during the first weeks of life and at wean age with some homozygotes surviving to adulthood. Those that survive to adulthood generally do not survive beyond one year. Pups have delayed hair growth such that the coat does not come in until 8 to 10 days of age. The skin, nails and mucosa have an orange pallor that persists throughout life and the feces are soft and also orange in color. Central phenotypes include hemolytic anemia, microspherocytosis, anisopoikilocytosys, polychromatophily, bilirubinemia, and splenomegaly with mild follicular hyperplasia. Although the spleen is of normal size at birth, at death adult splenic weight is three times normal and the architecture is disrupted. This is sometimes accompanied by hepatomegaly. The kidneys are discolored and have mild tubulonephrosis. Female homozygotes rarely become pregnant and do ..... For more information please see the full phenotype on the strain data sheet | ||

| Mice harboring the pEμSR-IL-14α transgene are viable and fertile, with expression of hemagglutinin-tagged human IL-14α (TXLNA or taxilin alpha) directed predominantly to the B lymphocyte compartment by the Eμ immunoglobulin heavy chain enhancer/SV40 promoter regions (from the pEμSR vector). Human IL-14α expression levels from the transgene are similar to mouse IL-14α expression levels observed in activated T cells/B cells. Transgene expression results in a phenotype with characteristics of systemic lupus erythematosus (SLE) and Sjogren's syndrome. Specifically, transgenic mice exhibit hypergammaglobulinemia (enhanced responses to T-dependent and T-independent antigens), autoantibodies, sialadenitis (infiltration of the parotid glands with lymphocytes), and mild immune-complex mediated nephritis with glomerular IgM deposition. In addition, almost all aged IL-14α-transgenic mice develop large B cell lymphoma (CD5+ B cell lymphoma) similar to .....

| 007176 | B6.Cg-Tg(Pax8-rtTA2S*M2)1Koes/J | Cryopreserved - Ready for recovery |
| Transgenic Pax8-rtTA mice are viable and fertile. These mice express an optimized reverse tetracycline-controlled transactivator (rtTA2S-M2) protein under the control of the murine Pax8 promoter, which directs expression to proximal and distal tubules and the collecting duct system of both embryonic and adult kidney. The rtTA2S-M2 variant of rtTA contains five amino acid changes in the TetR moiety (S12G, E19G, A56P, D148E, and H179R) and a synthetic optimized transactivating domain, resulting in reduced basal activity and enhanced doxycycline sensitivity compared to wild-type rtTA. When mated to a second strain carrying a gene of interest under the regulatory control of a tetracycline-responsive promoter element (TRE or tetO), expression of the target gene in kidney cells is induced with administration of the tetracycline analog, doxycycline (dox). These Pax8-rtTA mice provide a Tet-On tool that allows the inducible expression of genes in renal tubular epithelial .....

| The phenotype associated with the Nek1kat-2J allele is more severe than that of the Nek1kat allele. Mice homozygous for Nek1kat-2J all die before one year of age, a third of those that survive weaning die suddenly before 100 days of age, and the reported median survival age is 211 days. Mice homozygous for Nek1kat also have a shortened life expectancy with high pre-weaning mortality and a reported median survival of 286 days, but 22% were found to survive beyond 1 year. Both mutants are runted and have blunted noses with olfactory bulbs that are approximately half the normal size and lack most of the glomerular and external granular layers. In the brain there is dilation of the lateral and third ventricles, cerebral aqueduct and fourth ventricle along with large, fluid-filled cysts in the choroid plexus. Hydrocephalus occurs. Normochromic normocytic anemia is found and is more pronounced in Nek1Kat-2J ..... For more information please see the full phenotype on the strain data sheet | ||

| Mice homozygous for this targeted allele are viable, fertile and normal in size. No Fgf7 transcript is detected. By 2 months of age, the hair coat takes on a matted/greasy appearance that becomes more prominent with age. Homozygote kidneys are markedly smaller and posses structural anomalies. Morphometric analyses indicate a reduction (~30% of wildtype) in the total number of nephrons present. Kidney development appears to be effected as early as embryonic day 16.5. This mutant mouse strain represents a model that may be useful in studies related to kidney disease. | ||

| In this strain exon 1 of the endogenous mouse solute carrier family 9 (sodium/hydrogen exchanger), member 3 regulator 1 (Slc9a3r1, or Nherf-1) gene is disrupted by a neomycin (neo) resistance cassette, abolishing gene function. No homozygous females are obtained in the first 3 generations of backcrosses. Nherf-1-/- females obtained between F4 and F6 generations have 30-50% reduction in bodyweight over wildtype littermates, show impaired mobility, and some develop hydrocephaly. Most homozygous females die 30-35 days after birth due to reduced bone mineral density. Associated bone fractures are observed. Male homozygotes display an increase in urinary excretion of uric acid, a decrease in serum phosphate concentration, an increase in serum alkaline phosphatase, a 3-fold increase in urinary phosphate excretion, a slight increase in urinary magnesium excretion, but maintain normal overall renal function. Homozygotes also exhibit abnormalities in the targeting and sign ..... For more information please see the full phenotype on the strain data sheet | ||

Homozygous mutant mice show polydipsia and polyuria due to a defect in renal development. Cardiac fibrosis is evident in approximately 50% of the mice. PTGS2 deficient mice do not show altered inflammatory responses to in several tests of paw and ear edema; however, cytoxicity of hepatic cells induced by endotoxin was strikingly mitigated in these homozygotes.

| Mice homozygous for the Bcl2tm1Sjk targeted mutation appear normal at birth; however, growth retardation is evident by one week of age with considerable heterogeneity in weight compared to normal wildtype siblings (30% to 90%). There is some pre-weaning loss. Homozygotes succumb to renal failure as a result of polycystic kidney disease. Hematopoiesis, including lymphocyte differentiation is initially normal but the thymus and spleen decrease in size due to increased apoptosis. The coat color of homozygotes turns grey with the second hair follicle cycle. | ||

| At age E11.5 to E18.5, homozygous embryos exhibit hemorrhages and microaneurisms. Vascular defects persist into adulthood. At six weeks of age, mice are anemic (low hemoglobin concentration, red blood cell count, hematocrit). These mice also exhibit polychromasia (abnormally high number of immature blood cells); kidney defects (abnormally high blood urea nitrogen level, kidney size smaller than wild-type, swollen blood filled glomeruli, reduced number of vascular smooth muscle cells in glomeruli); abnormalities in palate bone fusion and abnormal neural crest derived and thoracic skeleton development. No gene product is detected in homozygous embryos aged ED9.5-12.5 or in adult gonad. Homozygotes occur at lower than Mendelian ratio (18%) and 8% die by age one week. Surviving homozygotes and heterozygotes are viable and fertile. These Zfp826 (BC055757)-mutant mice may be useful in studying cellular signaling in development and adult mice; specifically receptor tyrosine kinases (R .....

| Mice homozygous for this mutant allele (called BC058969 in the primary publication) are viable and fertile, with greater than 50% embryonic lethality observed in homozygous embryos. Homozygotes occur at a lower than Mendelian ratio (9%) from heterozygote x heterozygote crosses. No gene product is detected in homozygous embryos aged ED9.5-12.5 or in adult gonad. Homozygotes exhibit defects that affect the same cell types and processes as those controlled by the platelet-derived growth factor (PDGF) pathway, including vasculature, kidney, and skeletal defects (sternum and calvarial bones). Notably, 100% incidence of calvarial bones defects is reported. Additionally, homozygotes are reported to have low β-galactosidase activity; in situ hybridization or other sensitive methods may be necessary to detect expression of the lacZ-neo reporter fusion gene. These BC058969-mutant (2610005L07Rik-mutant) mice may be useful in studying cellular signal ..... For more information please see the full phenotype on the strain data sheet | ||

| Mice homozygous for this mutant allele are viable and fertile, with some incidence of perinatal lethality before two weeks of age (the Donating Investigator reports 18% of homozygotes die by two weeks of age). Homozygotes have abnormalities in palate bone fusion. Homozygotes exhibit defects that affect the same cell types and processes as those controlled by the platelet-derived growth factor (PDGF) pathway, including vasculature, kidney, and skeletal defects. These mutant mice may be useful in studying cellular signaling in development and adult mice; specifically receptor tyrosine kinases (RTK; such as Ras, MAP kinase, PI3K and those in the platelet-derived growth factor (PDGF) family) and immediate early genes (IEG) induced shortly after RTK activation. | ||
| 002332 | B6;129S4-Wt1tm1Jae/J | Cryopreserved - Ready for recovery |
| Mice homozygous for the Wt1tm1Jae targeted mutation die between embryonic days 13 and 15. They fail to develop a kidney or gonads. The hearts of homozygous mutant mice also fail to develop properly. Hearts are smaller than wildtype controls and possess a rounded apex. The right ventricular wall is thin and the left ventricle is reduced in size. There appears to be normal development of the aortic, pulmonary, mitral and tricuspid valves. Development of the diaphragm is also incomplete resulting in incomplete separation of the thoracic and abdominal cavities. Homozygous mutant lungs are also markedly smaller than wild type lungs. Heterozygous mice appear normal and show no tumor development (mice followed until 10 months of age). | ||
| 007207 | B6;129S4-Zfp640Gt(ROSA)81Sor/J | Cryopreserved - Ready for recovery |
| Mice homozygous for this Zfp640-mutant allele are viable and fertile, with abnormalities in palate bone fusion and increased weight gain observed only in males after adolescence. Homozygotes exhibit defects that affect the same cell types and processes as those controlled by the platelet-derived growth factor (PDGF) pathway, including vasculature, kidney, and skeletal defects. Additionally, homozygotes are reported to have low β-galactosidase activity; in situ hybridization or other sensitive methods may be necessary to detect expression of the lacZ-neo reporter fusion gene. These Zfp640-mutant mice may be useful in studying cellular signaling in development and adult mice; specifically receptor tyrosine kinases (RTK; such as Ras, MAP kinase, PI3K and those in the platelet-derived growth factor (PDGF) family) and immediate early genes (IEG) induced shortly after RTK activation. | ||
| 006208 | B6;129S6-Pdzk1tm1Dls/J | Cryopreserved - Ready for recovery |
| Mice homozygous for this targeted mutation are viable and fertile. Liver tissue from homozygous mutant mice lacks endogenous protein expression. Homozygotes, but not heterozygotes, have significantly decreased (~85-95%) hepatic high density lipoprotein (HDL) receptor scavenger receptor B-I (SR-BI) levels. This decrease is further exacerbated following diet supplementation with the PPAR-alpha activator fenofibrate. These mice may be useful in studies of cardiovascular health and atherosclerosis, lipid metabolism, SR-B1 regulation, kidney function, as well as kidney transporter (e.g. urate transporter) regulation and liver organic anion transport. | ||

| The Uoxin homozygous phenotype has incomplete penetrance. While 63% of Uoxin homozygotes die by 12-14 days of age, those that live to adulthood generally live a normal breeding life span. Homozygous adults display chronic polyuria, increased serum BUN and creatinine levels, and hydronephrosis with a concomitant inflammatory response that is followed by glomerular and tubular dilation.

| 000126 | B6By.Cg-Sd Mcoln3Va-J Krt25Re/J | Cryopreserved - Ready for recovery |
| Mice heterozygous for the varitint-waddler Jackson spontaneous mutation (Mcoln3Va-J) are more pigmented than the original varitint waddler mice (Mcoln3 Va) and behave normally although they are deaf. They have slightly diluted coat color, a large irregular belly spot, and white feet and tail tip. Homozygous mutant mice have extensive white spotting interspersed with patches of diluted color. They are deaf but behave normally and are fertile. Compound heterozygotes for the two alleles (Mcoln3Va-J/Mcoln3Va) are similar to Mcoln3Va-J/Mcoln3Va-J mice but are smaller with more white spotting and abnormal behavior. They are deaf and circle vigorously. Viability and fertility of Mcoln3Va-J/Mcoln3Va mice are considerably reduced. This strain is also carrying two other mutations, rex (Krt25Re) and Danforth's short tail (Sd). | ||

| The Sox18Ra and Sox18Ra-J alleles cause a less severe phenotype than the Sox18Ra-Op allele. The Sox18Ra and Sox18Ra-J alleles are similar mutations and give a very similar phenotype. The Sox18Ra allele has been more broadly described in the literature and will be covered here. Heterozygotes are viable and fertile. Heterozygotes have developmentally retarded sinus hair growth apparent at embryonic day 16.5 and retarded development of pelage follicles apparent by embryonic day 17.5. Thus, heterozygotes have slightly shorter vibrissae evident at birth, and can be distinguished at three days of age by their pink skin which, due to the abnormally sparse development of the coat, fails to darken like that of wildtype siblings. A paucity of fur is apparent by nine days of age and persists throughout life. Compared with the wild type pelage, Sox18Ra/+ coats have longer g .....

| Mice homozygous for the bpck deletion develop bilateral polycystic kidneys and die by 3 weeks of age. There is an increased incidence of hydrocephalus. Homozygotes can be identified by their smaller size and swollen abdomens. At 2 weeks of age elevated blood urea nitrogen is found. Ovaries and testes are smaller than normal and progression of maturing cells from spermatocytes to spermatids is disorganized at 3 weeks of age. The primary cilia on the kidney proximal tubule epithelial cells are dysmorphic and vary in length at birth and by 14 days of age cilia are significantly longer than normal. Through overlapping BAC rescues the polycystic kidney disease and hydrocephalus has been traced to the absence of the Tmem67 gene. Although lacking some of the ancillary phenotypes associated with Meckel Syndrome Type 3 in humans, this deletion offers a model for that disease. | ||
| 003301 | B6C3FeF1 a/A-Eya1bor/J | Cryopreserved - Ready for recovery |
| The human Branchio-Oto-Renal Syndrome is generally a dominant disorder with incomplete penetrance and variable expressivity resulting from null mutations in the EYA1 gene. The mouse Eya1bor allele is primarily a recessive hypomorphic mutation. Nevertheless, homozygous mice with this hypomorphic allele offer a good model for Branchio-Oto-Renal Syndrome. The phenotype of Eya1bor/Eya1bor mice parallels that of the human Branchio-Oto-Renal Syndrome and both are thought to result from reduced gene dosage. The Eya1bor/Eya1bor mice are deaf and their behavior is marked by circling and head-bobbing. They lack all but the most basal one-quarter of the cochlea, and the organ of Corti is completely absent. They have foreshortened, narrower semicircular canals and in some the common crus is incomplete. Their kidneys are absent or dysmorphic with greater severity generally on the left side. Fewe .....

| 004317 | BALB/cBy-Gulosfx/J | Cryopreserved - Ready for recovery |
| The sfx phenotype is not apparent until shortly after weaning age. By 26-30 days of age, homozygotes display decreased mobility, diminished weight gain, and more scruffy appearance than their heterozygous or wildtype siblings. Dissection reveals smaller spleen and thymus and increased kidney and brain weights. A reduction in bone mass is accompanied by a paucity of mature osteoblasts on bone surfaces, a subtle reduction of chrondrocytes in epiphyseal-plate columns, growth plate arrest in long bones, and other architectural abnormalities. Bone analysis shows sponteneous fractures both in large bones and smaller ones such as metacarpals. Serum analysis shows a decrease in calcium, inorganic phosphate, alkaline phosphatase, osteocalcin, and insulin-like growth factor 1. These homozygotes also have a reduction in the number of both the red and white blood cells. Homozygotes are fragile and must be handled with great care. (Beamer et al., 2000.) | ||

| Mice homozygous for the beige 2J spontaneous mutation (Lystbg-2J) display characteristics very similar to the original beige mutation (Lystbg). The mouse phenotype closely resembles Chediak-Higashi syndrome in man and similar conditions in mink and cattle. Abnormal giant lysosomal granules occur in all tissues with granule-containing cells, including granulocytes, lymphocytes, cells of the liver, kidney, central nervous system, pancreas, and thyroid, and the ducts of most glands; in type II pneumocytes; in mast cells; and in retinal pigment epithelium. Granulocytes from beige homozygous mutant mice show defective chemotaxis and reduced bactericidal activity. Beige mice are more susceptible than controls to pneumonitis and to various viral, bacterial, and parasitic infections. Natural killer (NK) cells from beige mice exhibit decreased endogenous cytotoxic activity. Beige mice also have a defective cytotoxic T-cell and cytotoxic antibody response to a .....

| The homozygous pearl phenotype includes hypopigmentation of hair and eyes, prolonged bleeding times associated with platelet storage pool deficiency (SDP) and lysosomal accumulation of ceroid pigment. This combination of abnormalities is characteristic of a human hereditary disease, Hermansky-Pudlak syndrome. Pearl mice also exhibit reduced sensitivity in the dark-adapted state, altered somatostatin binding to the retina, and an increased rate of renal apoptosis, making them a potential model for human congenital stationary night blindness. | ||

| The human Branchio-Oto-Renal Syndrome is generally a dominant disorder with incomplete penetrance and variable expressivity resulting from null mutations in the EYA1 gene. The mouse Eya1bor allele is primarily a recessive hypomorphic mutation. Nevertheless, homozygous mice with this hypomorphic allele offer a good model for Branchio-Oto-Renal Syndrome. The phenotype of Eya1bor/Eya1bor mice parallels that of the human Branchio-Oto-Renal Syndrome and both are thought to result from reduced gene dosage. During mapping crosses using CAST/Ei and C3H/HeJ, it was found that genetic background impacts both the kidney and inner ear phenotypes, and modifier genes in humans also may impact the severity of Branchio-Oto-Renal-Syndrome. | ||
| 001942 | C57BL-Bloc1s3rp/J | Cryopreserved - Ready for recovery |
| The reduced pigmentation (rp) mutation causes defects in organelle biogenesis. On a non-agouti background, mice homozygous for the recessive rp mutation have lighter coat color, pale ears and tail, and the eyes are dark. This coat color is similar in intensity to that caused by the cocoa or ruby eye-2 mutations, and there is no change in coloration with age. Homozygotes are viable and fertile, but have an increased bleed time, decreased splenic NK cell activity, and the melanosomes fail to properly mature (Gibb et al., 1981; Ahmed et al., 1989). There are fewer ellipsoidal type IV melanosomes, and the striated melanosomes are elongated but irregularly shaped indicating that rp disrupts the melanosomal maturation step II (Nguyen et al., 2002). These pigment granules are smaller than normal, but they are not found clumped together. Increased beta-galactosidase, beta-glucuronidase, and N-acetyl-beta-hexosaminidase activities are found in kidney homogenates of For more information please see the full phenotype on the strain data sheet | ||

| Mice homozygous for the targeted mutation, commonly referred to as B1RB2R -/-, are viable, fertile and display no major defects. At 4 months of age non-manipulated B1RB2R -/- mice exhibit no significant differences in blood pressure or kidney function when compared to Bdkrb2 deficient mice (Stock No. 006860). Fasted B1RB2R -/- mice exhibit significantly lower levels of plasma nitrite/nitrate compared to Bdkrb2 deficient mice. Post-ischemic B1RB2R -/- mice exhibit significantly higher plasma levels of urea nitrogen and creatinine, higher levels of oxidative nuclear and mitochondrial DNA modification, and increased rates of apoptosis and mortality than either wildtype or Bdkrb2 deficient mice. Histological evaluation of the kidney indicates that post ischemic B1RB2R -/- mice exhibit more severe histological changes in the renal proximal tubules than either wildtype or Bdkrb2 deficient mice (Kakoki, et al, 2007). This Bdkrb1/Bdkrb2 targeted ..... | ||
| 005921 | C57BL/6J-Aqp2F204V/J | Cryopreserved - Ready for recovery |
| Mice homozygous for this mutation are viable with normal body size and lifespan. Homozygotes are fertile, but females usually die during labor. The predicted valine for phenylalanine substitution at amino acid 204 of the mutant protein (F204V) leads to an enrichment in kidney cells of a normally short-lived, intermediately glycosylated 31 kDa isoform and to a reduction in the mature, glycosylated protein level. The mutant AQP2F204V protein is mis-localized in kidney collecting duct cells, and fails to translocate to the apical cell surface in response to desmopressin. Homozygous mice exhibit excessive water consumption and urination, normal plasma glucose levels, and no glucose in the urine. Mutant mice are unable to concentrate urine and exhibit severe hydronephrosis. The presence of some mature, glycosylated protein and a defective, but not completely absent, desmopressin response in homozygous mutant mice likely permits their survival. Heterozygous mice are viable and fer ..... For more information please see the full phenotype on the strain data sheet | ||

| The phenotype associated with the Nek1kat-2J allele is more severe than that of the Nek1kat allele. Mice homozygous for Nek1kat-2J all die before one year of age, a third of those that survive weaning die suddenly before 100 days of age, and the reported median survival age is 211 days. Mice homozygous for Nek1kat also have a shortened life expectancy with high pre-weaning mortality and a reported median survival of 286 days, but 22% were found to survive beyond 1 year. Both mutants are runted and have blunted noses with olfactory bulbs that are approximately half the normal size and lack most of the glomerular and external granular layers. In the brain there is dilation of the lateral and third ventricles, cerebral aqueduct and fourth ventricle along with large, fluid-filled cysts in the choroid plexus. Hydrocephalus occurs. Normochromic normocytic anemia is found and is more pronounced in Nek1Kat-2J ..... For more information please see the full phenotype on the strain data sheet | ||

| 002561 | C57BL/6J-Nek8jck/J | Cryopreserved - Ready for recovery |
| Mice homozygous for the Nek8jck mutation develop polycystic kidney disease. Histology revealed that the kidneys of some 3 day old pups from heterozygous parents had small isolated cysts lined by cuboidal epithelial cells, and 15 day old pups had cysts lined by flattened epithelia. Disease is progressive but not evident by kidney palpation until at least 4 to 5 weeks of age. Homozygotes generally remain active until shortly before death and usually die between 20 and 25 weeks of age. Homozygous females are fertile but do not consistently care for their litters; homozygous males are fertile but decreased fertility is reported after 15 weeks of age. No histologic abnormalities were found in the liver, spleen, or pancreas. (Atala et al., 1993) | ||

| 001594 | DBA/2J-Dtnbp1sdy/J | Cryopreserved - Ready for recovery |
| The autosomal recessive mutation sandy (sdy) takes its name from the lightened coat color first identified on the DBA/2J background. As early as 7-8 days of age the pinnae, feet, tail and fur are lighter in color than those of wildtype littermates and the lack of eye pigment is a defining trait at birth. The eye color does not darken with age unlike muted (mu) homozygotes. On the agouti C3H background, sandy homozygotes look like muted homozygotes, but on the non-agouti C57BL/6J or DBA/2J backgrounds, sandy homozygotes look like pallid (Pldnpa) homozygotes. The reduced pigmentation is linked to a storage pool deficiency. Sandy homozygotes have a prolonged bleeding time, in excess of 15 minutes, yet have normal platelet counts and normal sized platelets. Electron microscopy detects very few, if any, dense granules present in individual platelets of sandy homozygotes. Those that are detected are of normal size. Platelet serotonin levels are 7% that ..... For more information please see the full phenotype on the strain data sheet | ||

| acd/acd homozygotes can be distinguished from their wildtype (?/+) littermates by darkened pigmentation, short, curly vibrissae, smaller overall size, and abnormal pelage. Hair growth is retarded and lacks zigzag and guard hairs producing a sparse coat. There is heavy pigmentation in the nose, ears, body, feet and tail, and foci of melanin are also found in the skin and lymph nodes. Tail kinks or polydactyly of the hind feet are sometimes found and external genitalia are underdeveloped. It is rare for homozygotes to breed. Hydronephrosis is sometimes found in post-wean aged homozygotes resulting from focal hypertrophy of ureteral epithelium which causes ureteral blockage. The adrenals are abnormal in both males and females. Although the size of the medullary cells is normal, the cortical cells and nuclei are much larger than normal with nuclear inclusions and many mitochondria in the cytoplasm. These mitochondria have tubular cristae and cholesterol ester droplets, whic ..... For more information please see the full phenotype on the strain data sheet | ||

| These mice harbor a targeted mutation of the Na+/H+ exchanger isoform 3 locus (Nhe3 or Slc9a3) that abolishes endogenous gene expression. While no full-length mRNA is detected in kidney or intestine of homozygous mice, a truncated mutant mRNA lacking codons 320-831 (encoding sequences required for Na+/H+ exchange) is observed but expected to impart no dominant negative effects. When maintained as congenic on the FVB/N genetic background, homozygous mice exhibit a high mortality rate beginning just after weaning, with ~30% surviving to adulthood. Homozygous females are fertile, but homozygous males are infertile.
Homozygous (Nhe3-null) mice lack Na+/H+ exchanger isoform 3 function, and exhibit impaired intestinal absorption; resulting in severe diarrhea, altered salt and water homeostasis, and increased luminal fluid throughout the intestinal tract.

Abnormal giant lysosomal granules occur in all tissues with granule-containing cells, including granulocytes, lymphocytes, cells of the liver, kidney, central nervous system, pancreas, and thyroid, and the ducts of most glands; in type II pneumocytes; in mast cells; and in retinal pigment epithelium. Granulocytes from beige homozygous mutant mice mice show defective chemotaxis and reduced bactericidal activity. Beige mice are more susceptible than controls to pneumonitis and to various viral, bacterial, and parasitic infections. Natural killer (NK) cells from beige mice exhibit decreased endogenous cytotoxic activity. Beige mice also have a defective cytotoxic T-cell and cytotoxic antibody response to allogeneic tumor cells. Syngeneic tumor cells grow better in beige mice than in l ..... For more information please see the full phenotype on the strain data sheet | ||

| Mice homozygous for the jerker spontaneous mutation (Espnje) show behavior typical of the circling mutants - head-tossing, circling, and hyperactivity. Homozygous mutant mice are deaf from birth and have no detectable stimulus-related cochlear potential at any stage. The abnormal behavior and deafness are associated with postnatal degeneration of the sensory cells of the cochlea and the sacculus and utriculus in homozygotes. The primary influence of the jerker gene appears to be on the apical hair cells, not development of neural structures. Heterozygous jerker mice undergo a similar type of degeneration, but the onset is delayed. Auditory brainstem response is totally absent in homozygotes while heterozygous mice undergo a progressive impairment with age. Flexed tail homozygotes can be identified hematologically as earlyas embryonic day 13 and are detectably paler than normal by embryonic day 16, with most paler than normal by embryonic day 15. Homozygotes ar ..... For more information please see the full phenotype on the strain data sheet | ||
| 000262 | LS/LeJ | Cryopreserved - Ready for recovery |
| Mice homozygous for the lethal spotting mutation (Edn3ls) resemble piebald mice (Ednrbs/Ednrbs) mice. Homozygous mutant mice exhibit considerable white spotting and like homozygotes for the piebald-lethal allele (Ednrbs-l) usually develop megacolon. Lethal spotting mutant mice usually die in the third week of life from the megacolon abnormality, which is associated with deficiency of intrinsic ganglion cells in the lower colon. A few homozygotes may survive and breed. This strain is also homozygous for the black and tan coat color mutation (at). | ||

| 006956 | NOD.Cg-Vdrtm1Ska/CmatJ | Cryopreserved - Ready for recovery |
| Heterozygous mice are viable, fertile, and phenotypically indistinguishable from wildtype siblings. Homozygous mutant mice are viable but infertile. No VDR mRNA is detected by RT-PCR in samples from the intestine or kidney or from homozygous mutant embryo. Increased expression of CTP27B1 and reduced expression of CYP24A1 and calbindin-D9k is detected by RT-PCR in samples from VDR-deficient kidneys. Although mice homozygous for this targeted mutation are viable, shortly after weaning they exhibit dysmorphic features including a flat face and short nose, alopecia, growth retardation, and skeletal defects including hypocalcaemia, decreased bone mineral density, widened growth plates with hypomineralization, less trabeculae and thicker osteo seams. Homozygous mutant mice exhibit metabolic imbalances including abnormally high and low levels of 1,25(OH),2D3 and 25(OH)D3, respectively and abnormal cytokine and chemokine profiles.

| 000267 | ROP/GnLeJ | Cryopreserved - Ready for recovery |
| The Sox18Ra and Sox18Ra-J alleles cause a less severe phenotype than the Sox18Ra-Op allele. The Sox18Ra and Sox18Ra-J alleles are similar mutations and give a very similar phenotype. The Sox18Ra allele has been more broadly described in the literature and will be covered here. Heterozygotes are viable and fertile. Heterozygotes have developmentally retarded sinus hair growth apparent at embryonic day 16.5 and retarded development of pelage follicles apparent by embryonic day 17.5. Thus, heterozygotes have slightly shorter vibrissae evident at birth, and can be distinguished at three days of age by their pink skin which, due to the abnormally sparse development of the coat, fails to darken like that of wildtype siblings. A paucity of fur is apparent by nine days of age and persists throughout life. Compared with the wild type pelage, Sox18Ra/+ coats have l .....

| 002503 | ROP/Le-Os Ces1ca/+ Ces1ca/J | Cryopreserved - Ready for recovery |
| This strain originally was maintained segregating for Os and Ces1c, which are approximately 3 cM apart on Chr 8, such that Os and Ces1cb occurred in coupling opposite the wild-type Os allele and Ces1ca. In October 2002, it was discovered that a recombination event between Os and Ces1c had resulted in the strain's becoming fixed for Ces1ca. | ||
| 000268 | RSV/LeJ | Cryopreserved - Ready for recovery |
| Mice heterozygous for the varitint-waddler spontaneous mutation (Mcoln3Va) are deaf and show circling behavior, head-tossing, and hyperactivity. Heterozygotes circle somewhat less than some of the other circling mutants. Their coats are variegated with patches of normal-colored, diluted, and white fur. Homozygotes show more intense behavioral abnormalities than heterozygotes, and their coats are white, except for small patches of unaltered color near the ears and base of the tail. The pathological changes in heterozygotes include degeneration of the organ of Corti, stria vascularis, spiral ganglion, saccular macula, cristae ampullares, and vestibular ganglion. In homozygotes the degenerative changes are more severe and also include the utricular macula. Viability of heterozygotes is nearly normal, but fertility is reduced. Mortality is very high in homozygotes, and very few of the survivors are fertile. Compound heterozygotes for the two alleles (Mcoln3Va-J> .....

| 000269 | SB/LeJ | Cryopreserved - Ready for recovery |
| The SB/Le inbred strain is homozygous for both the satin (Foxq1sa) and beige (Lystbg) mutations. Most of the immunological phenotype is due to the beige mutation. Homozygous mutant beige mice are characterized by a condition that closely resembles Chediak-Higashi disease in man and similar conditions in mink and cattle. Abnormal giant lysosomal granules occur in all tissues with granule-containing cells, including granulocytes, lymphocytes, cells of the liver, kidney, central nervous system, pancreas, and thyroid, and the ducts of most glands; in type II pneumocytes; in mast cells; and in retinal pigment epithelium. Granulocytes from beige mice show defective chemotaxis and reduced bactericidal activity. Beige mice are more susceptible than controls to pneumonitis and to various viral, bacterial, and parasitic infections. They have a severe deficiency of natural killer (NK) cells.

| 002857 | STOCK Egfrtm1Mag/J | Cryopreserved - Ready for recovery |
| Mice homozygous for the Egfrtm1Mag targeted mutation are recognizable at 2 to 3 days by curly whiskers. The first coat is waved but later coats are not; vibrissae usually remain curled and the guard hairs curved. Fertile mutant females have impaired lactation. | ||
| 012892 | STOCK Slc26a1tm1Mark/J | Cryopreserved - Ready for recovery |
| Mice that are homozygous for the targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. Although a mutant mRNA gene product is detected by RT-PCR analysis of kidney tissue, no protein activity is detected in any tissue analyzed from homozygotes. Homozygotes exhibit reduced oxalate and sulfate transport in in isolated basolateral membrane vesicles from intestine, kidney and liver; infiltration of leukocytes around renal cortical vessels; calcium oxalate crystals and stones in kidney and bladder; elevated plasma oxalate levels and urinary sulfate levels; and increased acetaminophen-induced liver toxicity. Idua, iduronidase, alpha-L-, gene product (mRNA and enzyme activity) is normal in mice homozygous for the targeted mutation. | ||
| 008469 | STOCK Wnt9btm1.2Amc/J | Cryopreserved - Ready for recovery |
| Mice homozygous for the Wnt9bc allele are viable and fertile, with loxP sites flanking exon 2 of the targeted gene. When bred to mice that express Cre recombinase, the resulting offspring will have this region deleted in the cre-expressing tissue(s). Such deletion is predicted to result in out-of-frame splicing of exon 1 to exon 3, and consequently a mutant transcript that would encode a nonfunctional peptide comprising the first 27 amino acids of Wnt9b that includes the signal peptide. These Wnt9bc mice may be useful in generating conditional mutations for studying the role of Wnt9b (and other Wnt family members) in development and canonical Wnt signaling cascades, including metanephric kidney and urogenital system development. | ||
| 006619 | STOCK Tg(Cga-LHB/CGB)94Jhn/J | Cryopreserved - Ready for recovery |
| Hemizygous females are not fertile and hemizygous males are sub-fertile. Hemizygotes hypersecrete luteinizing hormone (LH) from pituitary gonadotropes under hypothalamic control. Inclusion of a bovine luteinizing hormone beta (LHB) sequence in the transgene results in a longer hormone half-life. Transgenic females display a range of reproductive and endocrine anomalies, while males are largely phenotypically normal. Transgenic males do not have elevated serum LH or testosterone when compared to wildtype animals, although their testes are significantly smaller. Transgenic females display elevated serum LH, androgens, and estrogens, with subsequent phenotypes including infertility with chronic anovulation and ovarian pathologies ranging from ovarian cysts to strain-dependent granulosa and theca-interstitial cell tumors. Tumors have been noted in mice from age 4 to 9 months. Other major phenotypes include hyperandrogenemia and precocious puberty, defects in uterine receptivity and mid-ges .....

| 000454 | WB.C3-Spna1sph/BrkJ | Cryopreserved - Ready for recovery |
| Homozygotes have spherocytic hemolytic anemia and neonatal jaundice. Erythrocytes have diminished biconcavity, a smaller than normal diameter, increased density, an appearance of exovesiculation, and a short lifespan. At birth homozygotes are very pale then become yellow during the first few hours of life and die generally within a day of being born. Although it is rare for a spherocytosis homozygote to survive beyond one day of birth on the WB/Re or C57BL/6J (stock #000450) congenic background, homozygotes on the (C57BL/6J x WB/Re)F1 background are much more robust and the majority survive to adulthood. Those that make it to wean age are expected to have a reasonable lifespan, sometimes living as long as a year. Thus, most studies of this mutation in the adult have been done on the (C57BL/6J x WB/Re)F1 background. These homozygotes display diminished hematocrit, decreased red blood cell count, very elevated red blood cell protoporphyrin levels, increased erythropoiesis, reticulo .....

| 017292 | B6.129X1(Cg)-Pkd2tm1.1Tjwt/J | Under Development - Now Accepting Orders |
| These Pkd2cond mutant mice possess loxP sites flanking exons 11-13 of the polycystic kidney disease 2 (Pkd2) gene. Mice that are homozygous for this allele are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. PKD2 is a calcium-permeable membrane channel expressed in fetal kidneys and in most adult tissues. Along with PKD1, PKD2 regulates cell proliferation, cell migration, and interactions with other cells, and is necessary for normal development and function of the kidneys. Mutations in PKD2 are responsible for 15% of all cases of autosomal dominant polycystic kidney disease (ADPKD). When bred to mice that express tissue-specific Cre recombinase, resulting offspring will have exons 11-13 deleted in the cre-expressing tissues. This strain may be useful for studying renal development in ADPKD.
For example, when crossed to a strain expressing Cre recombinase in endothelial cells (see Stoc ..... | ||
