| 000049 | C57BL/6J-KitW-v/J | Level 4 |
| 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. | ||
| 004104 | FVB.Cg-Mmp9tm1Tvu/J | Level 4 |
| Mice that are homozygous null for the Mmp9 gene are viable and fertile. No Mmp9 activity is detected in spleen cell lysates. Long bones (tibia, femur) are 10% shorter in homozygous null mice. Histological examination of 3-week-old mice reveals a dramatically lengthened zone of hypertrophic cartilage (6 to 8 times larger vs. wildtype) due to delayed apoptosis, vascularization, and ossification. Subsequent remodeling resolves the condition, resulting in normal appearing bones by 8 weeks of age. Null mice show altered responses to repair of injury in skin, cornea, central nervous system and bone marrow reconstitution, and altered inflammatory responses. | ||
| 000692 | WB/ReJ KitW/J | Level 4 |
| Kit mice possess pleiotropic defects in pigment-forming cells, germ cells, RBC's and mast cells.

| 100410 | WBB6F1/J-KitW/KitW-v | Level 4 |
| Kit mutant 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. KitW/KitW-v double heterozygotes are viable but sterile because of germ cell deficiency. They are also mast cell deficient. KitW/KitW-v double heterozygotes lack intermediate cells, derived from melanoblasts, in the stria vascularis resulting in endocochlear degeneration, loss of endocochlear potential, and hearing impairment. | ||
| 010672 | B6.129S4-Tnfrsf11btm1Eac/J | Repository- Live |
| Mice homozygous for this osteoprotegerin (OPG)-mutant allele are viable and fertile. While a smaller transcript is made from the disrupted allele, the spliced product is predicted to be out of frame and result in a nonfunctional protein. OPG-deficient mice exhibit dysregulation of osteoclast production leading to drastic changes in the bone architecture; homozygotes develop severe osteoporosis, gross deformations in bone structure, decreased bone density, and altered long bones physical dimension. Hematopoietic, B lymphocyte, and dendritic cell functions are also dysregulated.
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. | ||
| 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 | ||
| 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. | ||
| 000160 | B6.D2-KitlSl-d/J | Repository- Live |
| The multiple steel mutations (KitlSl) behave in a semidominant fashion and cause deficiencies in pigment cells, germ cells, and blood cells paralleling those caused by the Kit locus mutations (dominant spotting alleles). Most of the alleles at steel locus cause severe anemia in utero and death by 15 to 16 days of gestation in homozygous mutant mice. However, steel-Dickie homozygotes (KitlSl-d/KitlSl-d) and compounds of steel and steel Dickie (KitlSl/KitlSl-d) are viable, black-eyed white, are usually sterile in one or both sexes, and have severe macrocytic anemia. Heterozygous steel mice have a diluted coat color with a small amount of white spotting, are viable and fertile, and may have a slight macrocytic anemia. Primordial germ cells are absent in the nonviable steel homozygotes and severely reduced in steel Dickie and steel heterozygotes. Mast cells are virtually absent in skin and other tissu .....

| 007084 | B6.FVB(Cg)-Mmp9tm1Tvu/J | Repository- Live |
| Mice that are homozygous null for the Mmp9 gene are viable and fertile. No Mmp9 activity is detected in spleen cell lysates. Long bones (tibia, femur) are 10% shorter in homozygous null mice. Histological examination of three-week-old mice reveals a dramatically lengthened zone of hypertrophic cartilage (six to eight times larger vs. wild-type) due to delayed apoptosis, vascularization, and ossification. Subsequent remodeling resolves the condition, resulting in normal appearing bones by eight weeks of age. Null mice show altered responses to repair of injury in skin, cornea, central nervous system and bone marrow reconstitution, and altered inflammatory responses.

| 000231 | B6;C3Fe a/a-Csf1op/J | Repository- Live |
| Mice homozygous for the osteopetrosis spontaneous mutation (Csf1op) are viable and exhibit osteopetrosis. The osteoclasts are the primary cell type affected in homozygous mutant mice. This results in a generalized macrophage deficiency, monocytopenia, and defective bone remodeling. Homozygous mutant mice also have abnormal calcium regulation, impaired dental growth and female mice fail to lactate. Total leukocyte counts are reduced and marrow cells are decreased to one-tenth of normal control mice. Homozygous mutant mice have a deficient microglia and macrophage response, and therefore may be useful tools to study the role of glia in neurological disease if mated to transgenic models of neurodegenerative disease. | ||
| 008172 | BKS(HRS)-Ddr2slie/JngJ | Repository- Live |
| Mice homozygous for this mutation appear normal at birth. By weaning, they exhibit a reduced body mass, gain weight slower and display minor craniofacial abnormalities such as protruding eyes and a shortened snout. Bone mineral content, but not density is reduced in homozygotes. Plasma glucose levels are significantly increased while blood urea nitrogen levels are decreased in homozygotes. By six weeks, it can be seen that homozygous females lack a corpora lutea. By four months, homozygous males exhibit atrophy of spermatogonia, Sertoli and Leydig cells. This mutant mouse strain has characteristics similar to human Levi type dwarfism and may be useful in studies related to dwarfism and infertility. | ||
| 001768 | C3.Cg-Irs1Sml H2b/GrsrJ | Repository- Live |
| The small mutation causes hyperinsulinemia with only mild insulin resistance, a paucity of body fat, deficiencies in bone development and homeostasis, and hearing loss. Homozygotes can be distinguished by 2 weeks of age by their smaller body size and thin short tails, and adult homozygotes are visibly smaller with a tail that is 20% shorter than in wild-type controls. Hearing loss was shown through increased ABR threshold values when assessed between 8 and 12 weeks of age. The skeletal defects include shortened femurs with smaller growth plates, decreased cortical and trabecular thickness and abnormal trabecular number, with an increase in the number of osteoclasts and osteoblasts per bone perimeter but impaired osteoblast proliferation and differentiation in culture. This spontaneous point mutation is semidominant in some aspects of phenotype, unlike targeted mutations of this gene. Heterozygotes are statistically smaller than wild-type controls, but the severity of dwarfing is not ..... For more information please see the full phenotype on the strain data sheet | ||
| 012810 | C57BL/6J-Enpp1asj/GrsrJ | Repository- Live |
| Homozygotes initially appear normal but by 2 months of age they hold their forepaws closer to the body and develop a slow hobbling gait due to joint calcification. Moderate to severe hearing loss is found by 3 months of age. Homozygotes may breed, but the ability to breed and maintain a litter is curtailed by progressive physical disability. | ||
| 000811 | C57BL/6J-Ptpn6me-v/J | Repository- Live |
| Mice homozygous for the viable motheaten spontaneous mutation (Ptpn6me-v) develop severe autoimmune disease. Characteristics include by granulocytic skin lesions, pneumonitis, impaired humoral and cell-mediated immune responses, decreased responses to T cell and B cell mitogens and deficient cytotoxic T cell and NK cell activity. B cells are LY-1+. Homozygous mutant mice also exhibit hyperimmunoglobulinemia, and express multiple autoantibodies. Macrophages show increased proliferative capacity. In addition to defects in the immune system, viable motheaten mice show classic symptoms of osteoporosis due to an increased number and activity of osteoclasts in the bone marrow. The osteoporosis phenotype includes significantly lower bone mineral density and mineral content in the femurs of viable motheaten mice compared to normal littermate controls. In addition, these mice show reduced amounts of trabecular bone and decreased cortical thickness. The lifespan of homozygo .....

| The multiple steel mutations (KitlSl) behave in a semidominant fashion and cause deficiencies in pigment cells, germ cells, and blood cells paralleling those caused by the Kit locus mutations (dominant spotting alleles). Many steel alleles cause severe anemia resulting in death in utero of homozygous mutant mice. However, mice homozygous for some steel mutations and compound heterozygotes for two steel alleles (e.g., KitlSl/KitlSl-d) are viable and have black eyes and a white coat; they have severe macrocytic anemia, and both sexes are usually sterile due to failure of germ cells to migrate correctly during development. Mice heterozygous for a single steel mutation have diluted coat color with a small amount of white spotting, are viable and fertile, and may have a slight macrocytic anemia. Primordial germ cells are absent in the nonviable steel homozygotes and severely reduced in steel heterozygotes. Mast cells are virtuall .....

| 002134 | C57BL/6J-Mitfmi-vit/J | Research Strain |
| Mutations at the Mitf locus affect eye size, pigmentation, and the capacity for secondary bone resorption. Mice homozygous for the vitiligo spontaneous mutation Mitfmi-vit are only mildly affected compared to other Mitf alleles. Homozygous mutant mice have a lighter initial coat color than normal with extensive white spotting. After eight weeks of age, the mice producing increasing numbers of white hairs with each hair cycles resembling human vitiligo. Homozygotes exhibit uneven pigmentation of the retina and slow, progressive photoreceptor cell loss, eventually leading to blindness. | ||

| 006564 | B6(C)-KitW-41J 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. In appearance, homozygous KitW-41J mice are mostly white with black eyes and brown or grey spots. They are fertile, distinct from mice with other alleles of Kit, and have the impaired hemopoiesis causing mild, normochromic, macrocytic anemia. MPS VII mice are a model of the beta glucuronidase enzyme deficiency in humans called Sly Disease. They ..... For more information please see the full phenotype on the strain data sheet | ||
| 003142 | B6.129P2-Prlrtm1Cnp/J | Cryopreserved - Ready for recovery |
| There is complete female sterility due to abberant estrous cycles, abnormal preimplantation development of eggs, no implantation of blastocysts, lack of pseudopregnancy. Males show slightly delayed fertility. Mammary development is markedly affected. Homozygotes have no mammary development and do not lactate. Heterozygotes are unable to lactate after the first pregnancies, but attain some degree of lactation as they age or after multiple pregnancies. Serum prolactin levels are increased 60 - 100 fold in both males and females. Maternal behavior is diminished in pimiparous and nulliparous animals. Bone remodelling is decreased in homozygote mutants. | ||

| 000122 | B6.C3-KitW-44J/J | Cryopreserved - Ready for recovery |
| KitW-44J heterozygotes have white-tipped feet and a white tail tip although the belly spot standardly found in KitW* mutations is very small in this mutant, sometimes restricted to only a few hairs. Homozygotes have a flecked pelt that is predominantly white, especially ventrally, with pigmented patches particularly at the lateral borders. The pigmentation fades with age yielding black-eyed white mice by approximately 9 months of age. While many KitW-44J homozygotes are viable, fertility is diminished. Homozygous females have greatly reduced fertility and gonads that are smaller in size with reduced activity. Homozygous males are sterile although spermatogenesis occurs. The KitW-44J allele does not produce anemia in either its heterozygous or homozygous state. The red blood cell count, white blood cell count, hematocrit, and mean cell volume are normal. However, bone marrow transplantation experiments reveal that t ..... For more information please see the full phenotype on the strain data sheet | ||

| 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.

| Mutations at the Mitf locus affect eye size, pigmentation, and the capacity for secondary bone resorption. Mice homozygous for the white allele (MitfMi-wh) display an overall absence of pigment cells with the exception of the retina which expresses a few giving the eye a small amount of pigment. Homozygotes white mutant mice show slight microphthalmia but normal skeleton. Mice heterozygous for the microphthalmia (MitfMi) mutation have less iris pigment than wildtype and often have white spotting on the belly, head, and tail. Homozygous mutant mice have small eyes and are devoid of pigment in the eyes, inner ear, and skin. Homozygotes are deaf at an early age. There is a decrease of mast cells in the spleen and gut. Most homozygotes die around weaning but some may live for several months. There is a deficiency of secondary bone resorption (osteopetrosis) and the incisors fail to erupt. Immunological defects include decreased macrophage chemotac ..... For more information please see the full phenotype on the strain data sheet | ||

| Mice hemizygous for this transgene are viable. While males are fertile, transgenic females are unreliable breeders and mothers. Homozygotes are sterile. In both fetal and adult tissues, erythroid-specific expression of the transgene is observed. Transgenic mice have 120-150% greater mature body mass and increased bone mass. The donating investigator also reports transgenic mice have increased dermatological stiffness and toughness. Transgenic mice have a characteristic coat with few guard hairs compared to wildtype littermates. These mice may be useful in studies of bone formation and development, dermatology, and acromegaly. | ||

| 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 | ||
| 003728 | B6;129S-Sparctm1Hwe/J | Cryopreserved - Ready for recovery |
| Mice that are homozygous null for Sparc are viable and fertile. They display decreased physical activity when handled but otherwise appear normal. Sparc transcripts and protein products are not detected in these animals. The development of cataracts and osteopenia are the predominant phenotypes. Lenticular opacity starts to develop at 1 to 2 months after birth, progressing to mature cataracts by 5-8 months of age. Intracellular vacuoles are apparent at 1-2 months, leading to a disruption of fiber cell packing. In later stages, the lens capsule ruptures and displacement of lens material into the anterior chamber is evident. At 17 weeks of age, null mice exhibit 50% less trabecular bone than that found in wild type controls. The loss is 70% at 36 weeks. Decreases in both osteoclast and osteoblast numbers are observed, the cumulative effect of which is a negative bone-balance leading to profound osteopenia. | ||

| The multiple steel mutations (KitlSl) behave in a semidominant fashion and cause deficiencies in pigment cells, germ cells, and blood cells paralleling those caused by the Kit locus mutations (dominant spotting alleles). Most of the alleles at steel locus cause severe anemia in utero and death by 15 to 16 days of gestation in homozygous mutant mice. However, compounds of two steel mutants (e.g. KitlSl/KitlSl-d) are viable, black-eyed white, are usually sterile in one or both sexes, and have severe macrocytic anemia. Heterozygous steel mice have a diluted coat color with a small amount of white spotting, are viable and fertile, and may have a slight macrocytic anemia. Primordial germ cells are absent in the nonviable steel homozygotes and severely reduced in steel heterozygotes. Mast cells are virtually absent in skin and other tissues of steel mutant mice. Tumors tend to develop in germ-cell-deficient ovaries with adva ..... For more information please see the full phenotype on the strain data sheet | ||

| Both homozygous and heterozygous mice with the contrasted induced mutation (KitlSl-con) are viable. Male homozygous mutant mice are fertile but females are usually sterile. Mice heterozygous for the contrasted mutation are recognizable soon after birth by dark pigmentation of the genital papilla with the adult coat being slightly lighter than normal. Homozygous mutant mice also have dark genitalia and a markedly diluted coat and mild macrocytic anemia. | ||
| 003100 | C3Sn;129-Del(10AI646023-Ggt5)1Bayer/J | Cryopreserved - Ready for recovery |
| The dwarf-Bayer mutation (dwgBayer) occurred spontaneously in an embryonic stem cell line during genetic targeting of the insulin receptor gene. The phenotype of the mice resemble drawf grey (dwg, Stock No. 001743) and subsequent characterization determined that the two mutations are allelic. Homozygous mutant mice are grey and smaller in size than wildtype littermates. | ||

| 010825 | C57BL/6J-Ptpn6me/SzJ | Cryopreserved - Ready for recovery |
| Mice homozygous for the motheaten spontaneous mutation (Ptpn6me) develop severe autoimmune disease. Characteristics include granulocytic skin lesions, pneumonitis, impaired humoral and cell-mediated immune responses, decreased responses to T cell and B cell mitogens and deficient cytotoxic T cell and NK cell activity. B cells are LY-1+. Homozygous mutant mice also exhibit hyperimmunoglobulinemia, and express multiple autoantibodies. Macrophages show increased proliferative capacity. In addition to defects in the immune system, motheaten mice show classic symptoms of osteoporosis due to an increased number and activity of osteoclasts in the bone marrow. The lifespan of homozygous motheaten mice is approximately 3 weeks with death attributed to an autoimmune pneumonitis. | ||
| 006422 | C57BL/6J-hlb324B/J | Cryopreserved - Ready for recovery |
| Mice that are homozygous for the mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. Screening of third generation mice (G3) on standard chow identified a 12 week old male (born 9/30/2002) with a low bone mineral content and density as determined by DEXA analysis. Retesting at 18 weeks of age, when bone development has stabilized, confirmed this phenotype. This mutant mouse strain may be useful in studies of bone mineralization. | ||

| 001723 | CByJ.A-Ttc7fsn/J | Cryopreserved - Ready for recovery |
| Homozygous fsn mice suffer from hypochromic and normocytic anemia at birth which becomes more severe with age. The anemia makes the homozygous mice distinguishable as pups because of the pale color of ears and eyes. At 2 weeks of age focal epidermal hyperplasia and inflammation is evident with psoriasiform skin lesions becoming confluent and diffuse in 3-4 week old weanlings. The skin lesions progress to generalized alopecia and shedding of thick white scales. The gross lesions are accompanied by thickening and keratinization of the skin. A progressive paplosquamous disease ensues which is a model for some forms of psoriasis. fsn/fsn mice show hematocrit levels and red blood cell counts that are significantly decreased from birth through adulthood. Consequently the heart, liver and spleen become enlarged but the thymus weight is less than half normal. As the spleen enlarges, the mice also develop a potbellied appearance aiding in homozygous fsn identification. G ..... For more information please see the full phenotype on the strain data sheet | ||
| 000092 | FL/1Re-KitW/J | Cryopreserved - Ready for recovery |
| 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 are small at birth and have a transitory siderocytic hypochromic anemia due to defective heme synthesis in fetal but not adult reticulocytes. Fetal erythrocytes have more alpha hemoglobin synthesis than beta hemoglobin synthesis. Very high numbers of siderocytes are found at birth and this decreases during the first few weeks of life and stabilizes at approximately 3 weeks of age with 3% siderocytes, significantly higher than in wildtype adults. Most homozygotes have a belly spot and 1 to 5 flexures in the tail due to vertebral fusions. Vertebral fusions are also found elsewhere in the vertebral column. Fewer than expected homozygotes are generated indicating prenatal death and the postnatal death rate is approximately 4 times normal. A small minority of homozygotes have been .....

| 005710 | FVB.129S-Mmp13tm1Werb/J | Cryopreserved - Ready for recovery |
| Mice that are homozygous for this loxP-flanked ("floxed") allele are viable and fertile with normal endogenous gene function. Cre-mediated recombination results in replacement of exons 3-5 of targeted gene with a single loxP site. When bred to cre-expressing transgenic strains, these floxed mutant mice may be used to generate whole mouse or tissue-specific targeted mutants that may be useful in examining extracellular matrix remodeling and bone development. Of note: when these floxed mice are bred to mice containing a beta-actin promoter-driven cre transgene the resulting cre-positive, homozygous-null mice show robust accumulation of cartilage matrix caused by a transient expansion of the hypertrophic zone and increased trabecular bone mass that persists for months. | ||
| 000255 | GL/Le Edardl-J +/+ Ostm1gl/J | Cryopreserved - Ready for recovery |
| Mice homozygous for the grey-lethal spontaneous mutation (Ostm1gl) are characterized by osteopetrosis. Homozygous mutant mice are anemic, have a reduced white cell count, early thymic involution, and deficient calcium regulation. Homozygotes lack the power of secondary bone resorption. Consequently, the bones cannot grow normally, they do not form normal marrow cavities, and the teeth do not erupt. | ||
| 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.

| 010522 | STOCK Acancmd/NKruJ | Cryopreserved - Ready for recovery |
| Mice that are homozygous for this spontaneous mutation die just after birth from an in ability to breathe. Newborns exhibit cleft palate, a protruding tongue, bulging abdomen, enlarged liver and a shortened trunk, limbs, snout and tail. Long bones measure half the length of wild-type mice and the spinal column is reduced by 25%. Cartilage in homozygous mice consists of densely packed chrondocytes, little matrix, pycnotic cells and unusual amounts of collagen fibers. Mice that are heterozygous for the mutation appear normal at birth, but develop proportional dwarfism by 28 days. Aging mice exhibit spinal misalignment and degeneration followed by the sudden onset of a spastic gait and an accompanying decrease in movement. Mice die within one month following the appearance of the abnormal gait. Heterozygotes do not live beyond 19 months. This mutant mouse strain may be useful in studies of achondroplasia, disc herniation and spinal degeneration. | ||
| 001743 | STOCK Gtg1dwg/J | Cryopreserved - Ready for recovery |
| Mice homozgyous for the dwarf grey spontaneous mutation (Gtg1dwg) are viable but do not breed. Homozygous mutant mice have grey coats, are smaller than littermates, and develop cataracts by 3-4 weeks of age. Additional characteristics include increased numbers of osteoclasts, reduced bone mass, reduced red pulp area of the spleen, and slightly reduced thyroxin levels. | ||
| 000979 | STOCK KitlSl-16J/J | Cryopreserved - Ready for recovery |
| The steel mutations cause deficiencies in pigment cells, germ cells, and blood cells paralleling those caused by the Kit locus mutations. Most steel homozygous mice are severely anemic in utero and die usually at 15 to 16 days of gestation. However, compounds of two MgfSl mutants (e.g. MgfSl/MgfSl-d) are viable, black-eyed white, are usually sterile in one or both sexes, and have severe macrocytic anemia. Heterozygous mice have a diluted coat color with a small amount of white spotting, are viable and fertile, and may have a slight macrocytic anemia. Primordial germ cells are absent in the nonviable MgfSl/ MgfSl homozygotes and deficient in the MgfSl/+ heterozygotes. Mast cells are virtually absent in skin and other tissues of steel mutant mice. Tumors tend to develop in germ-cell-deficient ovaries with advancing age. | ||
| 001253 | STOCK MitfMi-wh +/+ Wnt7apx/J | Cryopreserved - Ready for recovery |
| Mutations at the Mitf locus affect eye size, pigmentation, and the capacity for secondary bone resorption. MIce homozygous for the white allele (MitfMi-wh) display an overall absence of pigment cells with the exception of the retina which expresses a few giving the eye a small amount of pigment. Homozygotes show slight microphthalmia but a normal skeleton. Heterozygotes (MitfMi-wh/+) have a diluted coat color, light ears, a white belly spot, and in rare cases a dorsal spot. In addition, they display abnormalitites of both the cochlear and vestibular portions of the inner ear. Mice homozygous for the postaxial hemimelia spontaneous mutation (Wnt7apx) have skeletal defects of the forelimbs. Digits 5, 4, and sometimes 3, are missing and there is a reduction or absence of the ulna. There is always a large oval foramen in the scapula. The hindlimbs are usually unaffected, but digit 5 may be absent, and occasionally the fibula is r ..... For more information please see the full phenotype on the strain data sheet | ||
