| 000659 | C3H/HeJ | Level 1 |
| C3H/HeJ mice are used as a general purpose strain in a wide variety of research areas including cancer, immunology and inflammation, sensorineural, and cardiovascular biology. C3H/HeJ mice and all other Jackson substrains are homozygous for the retinal degeneration 1 mutation (Pde6brd1), which causes blindness by weaning age. White belly spots, ranging in phenotype from a few white hairs to a defined spot are common in C3H/HeJ mice. There is also a high incidence of hepatomas in C3H mice (reportedly 72-91% in males at 14 months, 59% in virgin females, 30-38% in breeding females). Despite the lack of exogenous mouse mammary tumor virus (MMTV), virgin and breeding females may still develop some mammary tumors later in life. C3H/HeJ mice, fed an atherogenic diet (1.25% cholesterol, 0.5% cholic acid and 15% fat), fail to develop atherosclerotic aortic lesions in contrast to several highly susceptible strains of mice (e.g. C57BL/6J, Stock No. For more information please see the full phenotype on the strain data sheet | ||
| 001800 | FVB/NJ | Level 1 |
| FVB/NJ was inbred for the Fv1b allele which confers sensitivity to the Friend leukemia virus B strain. Due to the prominent pronuclei in their fertilized eggs and the large litter size, FVB/NJ mice are commonly used for transgenic injection. Compared to many other inbred strains, FVB/NJ is highly susceptible to asthma-like airway responsiveness with significant generation of antigen-specific IgE. Despite having the H2q MHC haplotype, FVB/NJ are resistant to collagen-induced arthritis. This resistance stems from coding polymorphisms in Tcra-V11.1 and a genomic deletion of some Tcrb-V genes that includes Tcrb-V8.2. FVB/NJ have higher than average activity, anxiety, and basal body temperature, low stress-induced hyperthermia, and are homozygous for the Pde6brd1 allele, which results in early onset retinal degeneration. Although FVB/N typically do not develop spontaneous tumors, they are highly susceptible to chemic ..... For more information please see the full phenotype on the strain data sheet | ||
| 000058 | B6(Cg)-Tyrc-2J/J | Level 2 |
| Mice homozygous for Tyrc-2J are phenotypically identical to homozygotes for the classic albino allele. Pigment is completely absent from skin, hair and eyes. While Tyr mRNA levels of Tyrc-2J homozygotes are similar to those of wild-type mice, there is virtually no tyrosinase protein present (Le Fur et al. 1996). Both homozygote and heterozygote mice are highly resistant to light damage and exhibit retinal degeneration (increased photoreceptor death) into young adulthood. Degeneration does not continue in adult mice (Bravo-Nuevo et al. 2004). | ||
| 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). | ||
| 000686 | SJL/J | Level 2 |
| SJL mice display a very high incidence of reticulum cell sarcomas resembling Hodgkin's disease by approximately one year of age. Sarcomas first appear in the Peyer's patches and mesenteric lymph nodes and later in the spleen, liver, thymus and other lymph nodes. Most of the tumors are mixed-cell types classified as type B reticulum cell neoplasms, but a few are type A histiocytomas. This strain is also characterized by extreme aggression in males and its susceptibility to experimental autoimmune encephalomyelitis (EAE) for multiple sclerosis research. SJL/J mice develop a spontaneous myopathy resulting from a splice-site mutation in the Dysferlin gene. This Dysfim allele has been shown to result in decreased levels of dysferlin protein in SJL/J mice and makes this strain a good model for limb girdle muscular dystrophy 2B. This spontaneous myopathy is characterized by a progressive loss of muscle mass and strength corresponding with an increase in muscle pathology incl .....

| 000635 | C3H/HeOuJ | Level 3 |
| C3H/HeOuJ mice are used as a general purpose strain in a wide variety of research areas including cancer and sensorineural, research. C3H/HeOuJ mice and all other C3H substrains at The Jackson Laboratory are homozygous for the retinal degeneration 1 mutation (Pde6brd1), causing blindness by weaning age. There is also a high incidence of hepatomas in C3H mice (reportedly 72-91% in males at 14 months, 59% in virgin females, 30-38% in breeding females). Despite the lack of exogenous mouse mammary tumor virus (MMTV), virgin and breeding females may still develop some mammary tumors later in life. | ||
| 000658 | C3HeB/FeJ | Level 3 |
| This general purpose strain shares a common origin with C3H/HeJ and C3H/HeOuJ. Unlike C3H/HeJ, it carries a normal allele at the Tlr4 locus, but is homozygous for Pde6brd1, which causes retinal degeneration. | ||
| 004326 | C3Bir.129P2(B6)-Il10tm1Cgn/Lt | Level 4 |
| Mice homozygous for the Il10tm1Cgn targeted mutation are viable and fertile when housed under specific pathogen free (SPF) conditions. Under conventional housing conditions, Il10-deficiency is associated with altered lymphocyte and myeloid profiles, elevated serum amyloid A levels, altered responses to inflammatory or autoimmune stimuli (both endogenous and induced), increased prevalence of colorectal adenocarcinoma (especially on 129/Sv and, to a lesser extent, BALB/c genetic background), and spontaneous development of chronic enterocolitis (see below). As The Jackson Laboratory Repository maintains these mice at high health status conditions (high SPF), the observed or experimentally-induced Il10-deficient phenotype may vary from that previously published using mice from conventional mouse rooms. These IL-10 mutant mice may be useful studying inflammatory bowel disease (IBD) (Crohn's disease (CD) and/or colitis), cancer, innate and adaptive immunity, a .....

| 002423 | NON/ShiLtJ | Level 4 |
| Although closely related to NOD mice, NON mice contain a diabetes resistant MHC haplotype (H2nb1 = Kb, Anb1, Ek, Db). The name was derived from "Non-Obese Non-diabetic"; however, NON/ShiLtJ mice should not be considered "normal." They carry the retinal degeneration (Pde6b) mutation and exhibit certain tendencies toward autoimmune disease. This strain maintains a low plasma insulin level, which may account in part why certain loci from NON/ShiLt can enhance development of autoimmune type 1 diabetes in segregating hybrid mice following outcross to NOD/ShiLtJ. The NON strain-characteristic immunologic abnormalities include perivascular/periductular leukocyte infiltration into the pancreas and submandibular salivary glands, and T lymphocytopenia evident by 20 weeks of age in spleen. NON/ShiLt mice clearly harbor genes predisposing to type 2 diabetes, as evidenced by early impaired glucose tolerance in males and females, d ..... For more information please see the full phenotype on the strain data sheet | ||
| 000680 | PL/J | Level 4 |
| PL/J mice show a moderate susceptibility to experimental allergic encephalitis (EAE) with late onset and high mortality. Reports of leukemia incidence vary from 50% in females and 19% in males to 80-90%. In addition to a low threshold to electroconvulsive seizures, PL/J mice are susceptible to handling and rhythmic tossing-induced seizures (Kitami et al. 2004) and very highly responsive to phytohemagglutinin (Heiniger et al. 1975). | ||
| 000689 | SWR/J | Level 4 |
| SWR/J mice are used widely in research as a general purpose strain. Aging mice exhibit a high incidence of lung and mammary gland tumors. They also develop extreme polydipsia and polyuria (nephrogenic diabetes insipidus) with increasing age. SWR/J mice are highly susceptible to experimental allergic encephalomyelitis (EAE). Germline deletion of about 50% of T-cell receptor V beta-chain gene segments and a T-cell receptor V alpha polymorphism are responsible for the resistance of SWR/J mice to collagen type II-induced arthritis. SWR/J mice show an intermediate susceptibility to developing atherosclerotic aortic lesions (1670 to 1690 um2 atherosclerotic aortic lesions/aortic cross-section) following 14 weeks on an atherogenic diet (1.25% cholesterol, 0.5% cholic acid and 15% fat). SWR/J mice have been recommended for generation and propogation of transgenic mice because they are high responders to exogenous hormones, have large and prominant pronuclei with good resistance to l .....

| 000692 | WB/ReJ KitW/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. The lack of germ cells in homozygous mutant mice leads to the development of some ovarian tumors (mesotheliomas and granulosa cell), associated with an overproduction of pituitary gonadotropic hormone. | ||
| 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. | ||
| 004337 | 129(Cg)-Foxg1tm1(cre)Skm/J | Repository- Live |
| This strain expresses Cre recombinase from the endogenous Foxg1 locus. Forkhead box G1 is required for telencephalon development and is expressed specifically in the telencephalon and discrete head structures. When crossed with a strain containing loxP site flanked sequence of interest, Cre-mediated recombination results in tissue-specific deletion of the target. Recombination occurs in the telencephalon, anterior optic vesicle (developing lens and retina), otic vesicle, facial and head ectoderm, olfactory epithelium, mid-hindbrain junction and pharyngeal pouches. Mice that are homozygous for the targeted mutation die perinatally. Heterozygous mutant mice are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. This mutant mouse strain represents a model that may be useful in studies of telencephalic development. | ||
| 013702 | B6.129(Cg)-Cep290tm1.1Jgg/J | Repository- Live |
| Homozygous Cep290 (centrosomal protein 290) targeted mutation neonates are runted and display retinal degeneration. Normal body weight is attained 1-2 months after birth. Both male and female homozygotes are sterile. This strain may be useful in studies of retinal degeneration, cilia/flagella development and fertility. | ||
| 006084 | B6.129P2(Cg)-Foxg1tm1(cre)Skm/J | Repository- Live |
| This strain expresses Cre recombinase from the endogenous Foxg1 locus. Forkhead box G1 is required for telencephalon development and is expressed specifically in the telencephalon and discrete head structures. When crossed with a strain containing loxP site flanked sequence of interest, Cre-mediated recombination results in tissue-specific deletion of the target. Recombination occurs in the telencephalon, anterior optic vesicle (developing lens and retina), otic vesicle, facial and head ectoderm, olfactory epithelium, mid-hindbrain junction and pharyngeal pouches. Mice that are homozygous for the targeted mutation die perinatally. Heterozygous mutant mice are viable, fertile, normal in size. On the C57BL/6 background, forebrain volume in heterozygotes is substantially reduced especially in the cerebral cortex (40.7%), striatum (29.7%), and hippocampus (18.6%). In the adult, the thalamus is reduced in volume by 21.6%. This mutant mouse strain represents a model that ma ..... For more information please see the full phenotype on the strain data sheet | ||
| 000537 | B6.BR-Agtpbp1pcd/J | Repository- Live |
| Mice homozygous for the Purkinje cell degeneration spontaneous mutation (Agtpbp1pcd) show a moderate ataxia beginning at 3 to 4 weeks. Homozygous mutant mice are somewhat smaller than normal but may live a fairly normal life span. Males have abnormal sperm and are sterile. Females are fertile but are poor breeders. There is rapid degeneration of nearly all Purkinje cells beginning at 15 to 18 days, and a slower degeneration of the photoreceptor cells of the retina and mitral cells of the olfactory bulb. Degeneration of Purkinje cells is followed by partial loss of granule cells. Discrete serotonin-immunoreactive fibers, which ascend to all three layers of the cerebellar cortex in normal controls, are of much higher density and form multidirectional contours in homozygotes. In the retina of homozygous mutant mice, pycnotic nuclei begin to appear in the photoreceptor cells between 18 and 25 days, and the outer rod segments become disorganized. Degeneration of the photor ..... For more information please see the full phenotype on the strain data sheet | ||
| 012910 | B6.Cg-Fxntm1Mkn Tg(FXN)YG22Pook/J | Repository- Live |
| The YG22 transgenic founder line carries a single copy of the human FXN gene with one GAA trinucleotide repeat sequence of 190 repeats. High levels of human FXN gene product (mRNA and protein) are detected by RT-PCR and Western blot analysis. 40-50% of the endogenous mouse Fxn gene product (protein) is detected by Western blot analysis in mice heterozygous for the targeted mutation alone. Mice that are homozygous for the targeted allele and hemizygous for the transgene exhibit an age dependent, tissue specific expansion of the GAA repeat, with expansion accumulation in the CNS (particularly cerebellum), similar to the human pathology. The GAA triplet repeat exhibits intergenerational instability. Mice that are homozygous for the targeted allele and hemizygous for the transgene exhibit progressive retinal degeneration, impaired and decreased locomotor activity and coordination, and an increase in body weight. At 9 months of age, muscle strength is decreased. Al ..... For more information please see the full phenotype on the strain data sheet | ||
| 007484 | B6.Cg-Tyrc-2J Tg(Tyr)3412ARpw Tg(Sry-EGFP)92Ei/EiJ | Repository- Live |
| On an albino background the X-linked transgene Tg(Tyr)3412ARpw permits visual identification of XX versus XY as early as embryonic day 10.5. This strain is segregating for Tg(Tyr)3412ARpw and homozygous for Tyrc-2J so the individuals not carrying Tg(Tyr3412)ARpw are albino. Because Tg(Tyr)3412ARpw inserted into the X Chromosome, breeding a carrier male with a noncarrier (wild-type) female results in embryos in which all XX individuals develop eye pigment, due to the Tg(Tyr)3412ARpw inherited from their father, while all XY individuals have non-pigmented eyes, having inherited a wild-type X Chromosome from their mother.
This strain is also homozygous for Tg(SryEGFP)92Ei. This reporter transgene consists of a 5 prime regulatory segment of the Sry gene driving EGFP. This transgene is expressed in the pre-support cell lineage (pre-sertoli and pre-granulosa cells) of the fetal genital ridge (Albrecht and Eicher, 2001) and in discrete areas the adult male but not ..... | ||
| 011122 | B6;129-Mertktm1Grl/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. In response to endotoxin, homozygotes exhibit an increase in spleen size and a decrease in monocyte response. Retinal photoreceptor epithelial cells fail to phagocytose outer segment membranes resulting in complete photoreceptor degeneration and blindness.
When combined with the mutations Tyro3tm1Grl (Stock No. 007937) and Axltm1Grl (Stock No. 011121) mice exhibit a lymphoproliferative disorder, autoimmunity, increased apoptosis in multiple tissues, abnormal spermatogenesis and reduced (in females) fertility or infertility (in males). This mutant mouse strain may be useful in studies of autoimmunity, germ cell development homeostatic regulation and apoptosis. | ||

| 000501 | B6CBACa Aw-J/A-Aifm1Hq/J | Repository- Live |
| Harlequin mice exhibit paucity of fur resulting in near baldness in hemizygous males and homozygous females. Heterozygous females have a patchy absence of hair that is not always obvious, since the degree of hair loss is notably less than 50%. Homozygotes and hemizygous males weigh less than heterozygous or wild type controls. Ataxia is noticeable by 5 months and progresses as the mice age. Initially the ataxia manifests itself as a side-to-side, unsteady gait with a lateral tremor visible at rest. A delayed cerebellar cortical atrophy has been characterized in these mutants, with an apoptotic loss of granule cells beginning at 4 months of age and a necrotic loss of Purkinje cells occurring subsequently. The granule cells re-enter the cell cycle, but the Purkinje cells do not, supporting the postulate that inappropriate cell cycle re-entry of terminally differentiated neurons can induce apoptosis. Cell loss is greater in the caudal lobules of the cerebellum and is extensive by 9 to 11 ..... For more information please see the full phenotype on the strain data sheet | ||
| 005252 | B6EiC3Sn.BLiA-Ts(1716)65Dn/DnJ | Repository- Live |
| Segmentally trisomic Ts(1716)65Dn mice provide a postnatal model for Down syndrome. Ts65Dn mice have three copies of most of the genes on mouse Chromosome 16 that are homologues of human Chromosome 21 genes. These extra genes, along with the centromere and about 5% of proximal Chromosome 17 are contained in a small extra chromosome derived from a reciprocal translocation. The trisomic mice on this genetic background, with the wild-type allele of Pde6b, are similar to the Ts(1716)65Dn trisomic mice (Stock No. 001924) in that they display slightly shorter body length and lower body weight, reduced grip strength, nocturnal hyperactivity, and impaired performance in the Morris water maze. Any differences in the Morris water maze tests for the two genetic backgrounds were found to be very subtle. Distinct from Stock No. 001924, this genetic background is homozygous for the wild-type allele of Pde6b a ..... For more information please see the full phenotype on the strain data sheet | ||
| 003647 | B6EiC3Sn.BLiAF1 | Repository- Live |
| This F1 hybrid is made using a C3H parent that is congenic for the wild-type allele of Pde6b. Thus, this F1 hybrid is useful for maintaining fragile mutations on a mixed background without the confounding retinal degeneration that is normally found in C3H strains. | ||
| 003237 | BALB/cByJ-Agtpbp1pcd-3J/J | Repository- Live |
| Mice homozygous for the Purkinje cell degeneration 3 Jackson spontaneous mutation (pcd3J) have an external and histological phenotype that is very similar to the original Purkinje cell degeneration mutation (pcd). Homozygous pcd mutant mice show a moderate ataxia beginning at 3 to 4 weeks, are somewhat smaller than normal but may live a fairly normal life span. Males have abnormal sperm and are sterile. Females are fertile but are poor breeders. There is rapid degeneration of nearly all Purkinje cells beginning at 15 to 18 days, and a slower degeneration of the photoreceptor cells of the retina and mitral cells of the olfactory bulb. Degeneration of Purkinje cells is followed by partial loss of granule cells. Discrete serotonin-immunoreactive fibers, which ascend to all three layers of the cerebellar cortex in normal controls, are of much higher density and form multidirectional contours in homozygotes. In the retina of homozygous mutant mice, pycnotic ..... For more information please see the full phenotype on the strain data sheet | ||
| 000653 | BUB/BnJ | Repository- Live |
| BUB/BnJ mice carry a specific T cell receptor V beta mutation, making this strain highly susceptible to collagen-induced arthritis. This T cell receptor V beta restriction works in concert with other uncharacterized modifying genes present in BUB/BnJ mice. BUB/BnJ mice carry no detectable endogenous ecotropic MuLV DNA sequences. Mice are also reported to have high serum complement activity. In response to challenge, BUB/BnJ mice develop immune-mediated nephritis characterized by proteinuria, glomerulonephritis and tubulointerstitial disease (Xie et al., 2004). BUB/BnJ mice are homozygous for the Mass1frings allele (monogenic, audiogenic seizure susceptibility 1) and are susceptible to audiogenic seizures prior to 25 days of age (Skradski, et al 2001). In addition, the Mass1frings allele acounts for early onset hearing impairment by 3-4 weeks of age (Johnson KR, et al 2005). | ||
| 000031 | BXD24/TyJ-Cep290rd16/J | Repository- Live |
| The BXD RI strains are used to study the genetics of behavioral phenotypes including alcohol and drug addiction, stress, and locomotor activity. The BXD set of RI strains also are used in the genetic analysis of numerous complex or potentially complex physiologic phenotypes including differences in organ weight and bone mineral density. The strain distribution pattern (SDP) for BXD RI strains is available through the Mouse Genome Informatics Recombinant Inbred Strain Distribution Patterns Query Form.
In 2004, a spontaneous mutation, rd16, was discovered in this recombinant inbred line. Mice exhibit complete degeneration of retinal photoreceptors (Seecharan et al. 2003) resulting in blindness. | ||

| 000480 | C3.MRL-Faslpr/J | Repository- Live |
| Mice homozygous for the lymphoproliferation spontaneous mutation (Faslpr) show systemic autoimmunity, massive lymphadenopathy associated with proliferation of aberrant T cells, arthritis, and immune complex glomerulonephrosis. Onset and severity of symptoms associated with the Faslpr allele is strain-dependent. For example, lymphoproliferation varies greatly with congenic strain C57BL/6J-Faslpr/Faslpr at a 24 fold increase over control lymph node weight, MRL/Mp-Faslpr/Faslpr at 75 fold and congenic strain C3H/HeJ-Faslpr/Faslpr highest at 116 fold increase over control lymph node weight (Morse et al 1985). Variance in renal pathology ranks from extensive in MRL/Mp-Faslpr/Faslpr at 4 to 7 months to negligible at 14 to 16 months in mice with C57BL/6J and C3H/HeJ backgrounds and homozygous for Faslpr> .....

| 003648 | C3Sn.BLiA-Pde6b+/DnJ | Repository- Live |
| One caveat to working with C3H inbred mice is the retinal degeneration caused by the Pde6brd1 mutation. This congenic has the wild-type allele of Pde6b from C57BL/LiA bred onto the C3H/HeSnJ background and thus offers most of the strain characteristics of the robust C3H background but without the early onset retinal degeneration. | ||
| 013148 | C57BL/6-Tg(Pdgfra-cre)1Clc/J | Repository- Live |
| Hemizygous Pdgfra-cre mice are viable and fertile, with cre expression directed to retinal Muller glial cells by the mouse Pdgfra (platelet derived growth factor receptor, alpha polypeptide) promoter. Expression is predominantly in the cell bodies of the inner nuclear layer (INL) of the retina, but some expression may be observed in the outer nuclear layer (ONL) and in the ganglion cell layer (GCL). The donating investigator indicates that although not examined, cre may also be active in many types of central nervous system glial cells. When bred with mice containing a loxP-flanked sequence of interest, Cre-mediated recombination will result in deletion of the floxed sequence(s) in the offspring. | ||
| 004624 | FVB.129P2-Pde6b+ Tyrc-ch Fmr1tm1Cgr/J | Repository- Live |
| Mice that are homozygous for the targeted mutation are viable and fertile. Quantitative morphological analysis of dendritic spines of visual cortex pyramidal cells reveals mutant mice have more long dendritic spines, fewer short dendritic spines and more spines with an immature morphology than wildtype littermates. These mice were backcrossed for 11 generations onto the FVB background, are homozygous for the 129P2/OlaHsd wildtype Pde6b allele and do not suffer from blindness due to retinal degeneration. This mutant mouse strain may be useful in studies related to Fragile X Syndrome. | ||
| 004828 | FVB.129P2-Pde6b+ Tyrc-ch/AntJ | Repository- Live |
| These mice are homozygous for the 129P2/OlaHsd wildtype Pde6b allele and do not suffer from blindness due to retinal degeneration. Mice from the colony of FVB.129P2-Fmr1tm1Cgr/J, Stock No. 004624, that no longer carried the mutant allele for Fmr1 were used to establish this line. Mice are pigmented as a result of the homozygosity of the Tyrc-ch allele. This mutant mouse strain may be useful in studies where a sighted mouse on the FVB background is an appropriate control, such as behavioral studies. This strain serves as the control for the FVB.129P2-Fmr1tm1Cgr/J strain, Stock No. 004624 . | ||
| 003257 | FVB/N-Tg(GFAPGFP)14Mes/J | Repository- Live |
| Transgenic mice overexpress Green Fluorescent Protein under the control of the astrocyte-specific glial fibrillary acidic protein promoter. Bright fluorescence is observed in the cell bodies and processes of unfixed or fixed astrocyte preparations throughout the CNS of hemizygous mice. In addition retinal Mullers cells expressed the GFP transgene in response to degeneration of neighboring photoreceptors. These mice provide a method to follow changes in astrocyte morphology during development or disease processes. | ||
| 002374 | FVB/N-Tg(MMTV-PyVT)634Mul/J | Repository- Live |
| Mice carrying the (MMTV-PyVT) transgene are viable, but show loss of lactational ability coincident with transgene expression. Female carriers develop palpable mammary tumors as early as 5 weeks of age. Adenocarcinomas arise in virgin and breeder females as well as males, which are multifocal, highly fibrotic, and involve the entire mammary fat pad. Males also develop adenocarcinoma of the seminal vesicles and hemangiomas. Pulmonary metastases are observed in 80-94% of tumor-bearing female mice. Transgene expression is detected at high levels in male and female mammary glands. Lower levels are detected in salivary gland, seminal vesicles, ovaries, and lungs (believed to be the result of pulmonary metastases). | ||
| 002856 | FVB/N-Tg(TIE2-lacZ)182Sato/J | Repository- Live |
| Transgenic mice carry a beta-galactosidase reporter gene under the control of the murine Tek (Tie2) promoter. LacZ is expressed specifically in vascular endothelial cells in embryonic and adult mice. The transgenic line may be useful when crossed with tumor producing strains and the transgene used to visualize neovascularization during tumorigenesis. | ||

| A 7 base pair deletion was reported in the Cd4 5' untranslated region of MOLF/EiJ (Wade et al. 1993, Capparelli et al. 2004). Subsequent testing at The Jackson Laboratory indicated that MOLC/EiJ, MOLD/EiJ and MOLG/EiJ also carry the variant sequence. The deletion is not believed to affect gene expression. | ||
| 000679 | P/J | Repository- Live |
| P/J mice exhibit a high incidence of lymphatic leukaemia. They also show a high susceptibility to audiogenic and electroconvulsive seizures. P/J mice are also homozygous for a number of other mutations including nonagouti (a), brown (Tyrp1b), pink-eyed dilution (Oca2p), short ear (Bmp5se), dilute Myo5ad), and retinal degeneration 1 (Pdeb1rd1). | ||

| The RBF inbred strain arose from crosses with wild mice, originally known as "tobacco mouse", captured in Valle di Poschiavo in S.E. Switzerland. The wild mice originally known as 'tobacco mouse' because of the coat colour. The strain was transferred to Dr. M. Davisson (Dn) in 1981 and subsequently to the production colony of The Jackson Laborotory (J). Mice are homozygous for Robertsonian translocation Rb(1.3)1Bnr, Rb(8.12)5Bnr and Rb(9.14)6Bnr. This strain is useful for production of antibody producing hybridomas. | ||

| Mice that are homozygous for the targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. These mutant mice are photosensitive and if not maintained under low light conditions will develop progressive retinal degeneration. No gene product (protein) is detected by Northern blot analysis of retinas from homozygous mice maintained in cyclic (12 hour light: 12 hour dark) conditions. Photoreceptor loss in homozygotes maintained in cyclic light conditions begins at approximately 100 days of age, progressing to loss of more than half of the photoreceptors by 1 year of age. After 1 week of constant light exposure, homozygotes lose 30% of photoreceptors; after 3 weeks of constant light exposure, more than 60% of photoreceptors are lost. Homozygotes maintained under cyclic light conditions exhibit disorganized and 25% shorter retinal rod outer segment layer, as well as reduced levels of retinal rhodopsin. Recovery phase respon .....

Cre activity is demonstrable in brain area neurons involved in the control of food intake (arcuate nucleus (hypothalamus) and solitary tract nucleus (hindbrain)). When bred with a mouse containing a loxP site-flanked sequence of interest, Cre-mediated recombination results in deletion of the flanked genome in tissues that normally express Pomc1.

| 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.

| Male and female mice homozygous for rd6develop a slowly progressive retinal degeneration affecting both rod and cone cells beginning at 3-4 weeks of age, soon after the retina develops. Ophthalmoscopic examination reveals small, evenly distributed white spots throughout the retina from the time the mice are 8 weeks old. The spots remain clearly visible until about 7 months, when clinical signs of retinal degeneration first become evident, and become less easily distinguishable as degeneration progresses. Retinal blood vessels appear pale and attenuated by 7 months and are undetectable by 15 months, when the fundus appears mottled, lightly pigmented and granular. Aberrations of the photoreceptor layer are histologically evident at 3-4 weeks; by one year, only one to three cell layers (of the normal 10-12) remain. The time and distribution of the ophthalmoscopically detectable retinal spots correlate with histologic observation of putative phagocytic cells in the subretinal space .....

Whorls and rosettes in the outer nuclear layer can first be detected at 12.5 days of age, before the eyes open. These whorls likely underlie the appearance of the white spots on the retina and the white spots and whorls are both present at one month of age then are reduced in number by 5 months, and disappear by 16 months. Electroretinographs give normal signals until 5 months of age when both rod and cone signals begin to show a progressive reduction.

| Belly spot and tail (Rpl24Bst) is a semidominant, homozygous in utero lethal mutation. Adult heterozygotes are viable and fertile although a reduced birth rate for heterozygotes has been reported. This may reflect incomplete penetrance, or, more likely, prenatal mortality. The Rpl24Bst mutation has variable expressivity and the heterozygous phenotypic traits include shortened and kinked tail, white feet and belly spot, malocclusion, smaller body size, exencephaly, abnormalities of the spine, ocular defects, and polydactyly. Polydactyly is found predominantly in the right rear paw, occasionally in the left front paw and rarely in the left rear or right front paws. Approximately 50-60% of the heterozygotes have a reduction in pupillary light reflex in one or both eyes due to an underlying optic nerve atrophy.

| Mice homozygous for the targeted allele are viable, fertile, normal in size, and do not display any behavioral abnormalities. No endogenous or truncated protein product was detected in thymocytes or T cells. Mature T lymphocytes from null mice have blunted proliferative responses with decreased levels of both IL-2 and IL-2 receptor, and defective T cell receptor-initiated IkappaB-degradation/NF-kappaB activation. Homozygous mice exhibit severely impaired Th2, but normal Th1, immune responses as well as abnormal insulin signaling and glucose transport. Mutant mice also have defective regulatory T cell development (very low CD25 expression). This mutant may be suitable for use in studies related to T cell proliferation/signal transduction/immunodeficiency, Th2-mediated disease, asthma, and diabetes.

The Ttpa protein product is required for the maintenance of proper alpha-tocopherol levels, the major form of vitamin E in plasma and tissues. The absence of Ttpa protein product in homozygous-null animals results in a corresponding 95% reduction in alpha-tocopherol. Low levels of alpha-tocopherol render female mice infertile, a condition that can be addressed with vitamin E supplements. Male fertility is unimpaired. These mice provide a viable model for studying vitamin E deficiency. | ||

Homozygous mutant mice display abnormal proteolipid storage by lysosomes termed neuronal ceroid lipofuscinosis. Mice also develop progressive retinal degeneration at an early age. Affected neuronal lysosomes show abnormal morphology. Severe cerebral gliosis and Wallerian degeneration of long neuronal tracts occur late in the disease and account for the motor neuron abnormalities and eventual paralysis.

| Mice hemizygous for this "Trc-Tox176" transgene (also called "h-GNAT2pro-DTA") are viable and fertile. Expression of diphtheria toxin (DTA) from the transgene is similar to that of endogenous GNAT2, leading to ablation of both rod and cone photoreceptor development in the ventral retina (the abnormality is a result of abnormal cellular development rather than a consequence of retinal degeneration). The dorsal retina has nearly normal development of rods, but the development of cones is limited to about 10%. These transgenic mice exhibit an absence of cone photoreceptors in the retina, as well as the concomitant absence of rod photoreceptors in the ventral retina. The mice may be useful in studies of photoreceptor development, photoreceptor-related retinal diseases, and to profile photoreceptor genes in adult and in developmental stages. | ||

| Mice homozygous for the motor neuron degeneration (mnd) spontaneous mutation show onset of disease between 5 and 11 months. Disease characterics include hindlimb weakness and ataxia which progresses to severe spastic paralysis of all limbs, with death usually by 9 to 14 months. Histological examination of the nervous system of affected animals shows sudanophyllic, autofluorescent intraneuronal inclusions characteristic of human neuronal ceroid lipofuscinosis suggesting that mnd mice are models for such human disease as Batten's disease. Performance at 14-16 weeks of age in an associative learning task is significantly decreased relative to controls, thus providing an early disease phenotype for this neuronal ceroid lipofuscinosis model. (Wendt KD, et al., 2005) Males and females are equally affected and both are fertile, although breeding efficiency is reduced.

| 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 (protein) is detected by Western blot analysis of eye tissue. Progressive loss of electroretinograms (ERGs) of cone cells from homozygotes begins at age 3 to 5 weeks. ERGs are completely lost in mice older than 8 weeks of age. Histological analysis of mutants between 4 and 5 weeks of age reveals retinal cone cell atrophy and a reduction in the number of cone cells. Isolated retinal rod cells exhibit reduced a-wave and b-wave ERGs, and impaired photoresponse. This mutant mouse strain may be useful in studies of incomplete achromatopsia, progressive cone-rod dystrophy, retinitis pigmentosa and Leber congenital amaurosis. | ||

| Mice homozygous for the Purkinje cell degeneration spontaneous mutation (pcd) show a moderate ataxia beginning at 3 to 4 weeks. Homozygous mutant mice are somewhat smaller than normal but may live a fairly normal life span. Males have abnormal sperm and are sterile. Females are fertile but are poor breeders. There is rapid degeneration of nearly all Purkinje cells beginning at 15 to 18 days, and a slower degeneration of the photoreceptor cells of the retina and mitral cells of the olfactory bulb. Degeneration of Purkinje cells is followed by partial loss of granule cells. Discrete serotonin-immunoreactive fibers, which ascend to all three layers of the cerebellar cortex in normal controls, are of much higher density and form multidirectional contours in homozygotes. In the retina of homozygous mutant mice, pycnotic nuclei begin to appear in the photoreceptor cells between 18 and 25 days, and the outer rod segments become disorganized.

| Visibly, Grm1rcw/Grm1rcw mice are identifiable by 2.5 - 3 weeks of age. Their constant wobbly gait frequently throws them off balance, but only briefly, as they show immediate and normal righting response. When walking, they often brace for balance with their fore- and hindfeet extended forward or sideways. Their heads lurch mildly and the mutants often sit on their haunches when motion falters. Their forefeet show normal grip strength when the mutant mice are pulled gently backwards over a cage cover. When picked up by the tail, they may clasp their hindfeet. However, they show sufficient hindlimb strength to prevent their falling when placed on an edge. Mutants live through adulthood, and mice of both sexes breed.

| Mice homozygous for the Il10tm1Cgn targeted mutation are viable and fertile when housed under specific pathogen free (SPF) conditions. Under conventional housing conditions, Il10-deficiency is associated with altered lymphocyte and myeloid profiles, elevated serum amyloid A levels, altered responses to inflammatory or autoimmune stimuli (both endogenous and induced), increased prevalence of colorectal adenocarcinoma (especially on 129/Sv and, to a lesser extent, BALB/c genetic background), and spontaneous development of chronic enterocolitis (see below). As The Jackson Laboratory Repository maintains these mice at high health status conditions (high SPF), the observed or experimentally-induced Il10-deficient phenotype may vary from that previously published using mice from conventional mouse rooms. These IL-10 mutant mice may be useful studying inflammatory bowel disease (IBD) (Crohn's disease (CD) and/or colitis), cancer, innate and adaptive immunity, a .....

| 000229 | C3Fe.CGr(Cg)-nr/J | Cryopreserved - Ready for recovery |
| Nervous homozygotes on this C3HeB/FeJ congenic background display a mutant phenotype by 3 to 4 weeks of age, much earlier than on the BALB/cByJ background (see Stock No. 003756). Because this earlier onset occurs at wean age, the affected pups may have to stay with the mother an extra week or two. Homozygotes are somewhat smaller than their littermates and are ataxic with a slight head bobbing motion but do not display tremors. They often fall over on their side and have a sort of backwards lurching movement. They have a tendency to look up and are hyperactive compared to their littermates. Males and females are equally affected and have a normal lifespan. They are poor breeders with a higher than normal incidence of non-productive matings. A cross between C3Fe.CGr(Cg)-nr/J homozygotes and BALB/cByJ-nr/J homozygotes produced compound heterozygotes most of which presented with the nervous phenotype by 4 weeks of age, .....

| 001904 | C3H-Atcayji-hes/J | Cryopreserved - Ready for recovery |
| Mice homozygous for the hesitant spontaneous mutation (Atcayji-hes) can be recognized at 14 days of age by their slightly smaller size and hesitant walking motion. From 3 weeks of age on, the hindlimbs of homozygous mutant mice hesitate after lifting and then are placed flat on the surface and stiffly extended causing the posterior to rise. No body tremors, spasticity, or muscle degeneration is observed. Homozygotes of both sexes are fertile, although fertility in males may be reduced. | ||
| 000511 | C3H/HeJ-Ap3d1mh-2J/J | Cryopreserved - Ready for recovery |
| The mh-2J allele of Ap3d causes a similar yet less severe pigment dilution than that caused by the mh allele, but each causes a different neurological phenotype. These homozygotes are recognizable by a lighter coat color and decreased pigmentation in the eyes. For the Ap3dmh allele, this coat color dilution has been shown to result from smaller and fewer melanin granules in the hairs. While both alleles cause similar degrees of hyperactivity, the cochlear degeneration and accompanying head tilt is observed less frequently in the Ap3dmh-2J homozygotes and the auditory evoked brain responses in these mice are similar to wildtype. At three months of age, mice homozygous for the Ap3dmh allele have significantly increased auditory evoked potentials after the first of two paired tones. Ap3dmh-2J homozygotes also show an increased response to the first tone, but this has not been proven with stat ..... For more information please see the full phenotype on the strain data sheet | ||

| Mice homozygous for the Faslgld mutation display lymphadenopathy and systemic autoimmunity similar to that in Fasllpr homozygous mice. There is significant enlargement of all lymph nodes to 50 times the control weight by 20 weeks of age. Homozygotes also have an enlarged spleen, greatly increased numbers of T, B, and null lymphocytes and develop immune complex glomerulonephrosis. Onset of symptoms is dependent on genetic background with the C3H/HeJ strain having the earliest onset exhibiting glomerulonephritis by 22 weeks. | ||
| 002433 | C3H/HeJ-Spnb4qv-lnd2J/J | Cryopreserved - Ready for recovery |
| Mice homozygous for the recessive Spnb4qv-lnd2J mutation are identifiable by two weeks of age by their small size relative to their littermates. Their bodies quiver, and their movements are less coordinated than those of littermates. Mutants become progressively wasted and die by four weeks of age. (Cook 1995; Samples 2003) Their phenotype is more severe than that of mice homozygous for the original Spnb4qv-lnd allele, which survive at least 10 months. Spnb4qv-lnd/Spnb4qv-lnd mice were found to have dystrophic axons in the lower lumbar and sacral spinal cord. The dystrophic axons were observed in both white and gray matter, but particularly in dorsolateral white matter (Bronson et al. 1992). The acoustic brainstem response ABR) pattern of Spnb4qv-lnd2J homozygous mice exposed to click stimuli of 80, 70, 60 and 50 decibels exhibited only the first expected peak, indicating the mice have norm .....

| 005972 | C3H/HeJBirLtJ | Cryopreserved - Ready for recovery |
| Under conventional housing conditions, C3H/HeJBirLtJ mice develop spontaneous colitis. It should be noted that the phenotype of cecocolitis in this strain requires an interaction with an as yet undefined component of the enteric flora. Inflammation is present mainly in the cecum and right colon. Colitis develops early in life and resolves by three months of age. The colitis is characterized by acute and chronic inflammation, ulcerations, crypt abscesses, regenerative hyperplasia and submucosal scarring. A mild recurrence of the disease can occur after one year. Small lesions at the anorectal junction are common throughout life. | ||

| 002235 | C3H/HeSnJ-Ctnna2cdf/J | Cryopreserved - Ready for recovery |
| Cerebellar deficient folia (cdf) is a recessive mutation which maps to chromosome 6. Homozygotes display a constant side-to-side wobble in their gait that is apparent as early as 2 weeks of age. Additionally, they often hold their tails off the surface or arch them over their heads while moving. Smaller size is detectable in homozygotes by two weeks of age, at weaning they weigh approximately 25% less than littermate controls, and as adults they weigh, on average, 50% less. These mutants live a normal life span (one-and-a-half to two years on the C3H/HeJ background), but homozygous males rarely breed and homozygous females are poor mothers requiring transfer of litters to foster mothers. The cdf mutation causes a hypoplastic and dysmorphic cerebellum. On the C3H/HeJ background, homozygotes have only 7 cerebellar folia rather than the 10 present in wildtype, and the folia pattern is abnormal. Their vermis is one-third smaller than wildtype in rostro-caudal length ..... | ||

| On an agouti background gri homozygotes resemble Tyrc-ch homozygotes. There is a graying of the coat due to a lighter than normal phaeomelanin band. There is no change in eye color. gri homozygotes are slightly smaller than their unaffected littermates. Homozygous females breed well, but homozygous males often do not breed. Testis biopsies failed to identify any sperm abnormalities. The gri mutation does not cause a clotting disorder. (Davisson et al., 2000.) | ||

| 002588 | C3HeB/FeJ-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. 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. | ||

Dystrophic axons also common throughout the brain stem. In the forebrain, some can be seen in the optic nerves and tracts, corpus callosum, rostral commissure, and fornix. Mutant mice are identifiable between 2 and 3 weeks of age by their small size, dull fur, and nervous behavior. Adults are smaller than littermates and have a humped back and slender torso. They walk with a shaky gait and restricted hip movement. Hindlimbs paralyzed by 8 months of age. They rarely breed. | ||

| Homozygotes exhibit grainy retinas by 3 weeks of age which progresses into large white patches distributed across the entire retina by 12 weeks of age. At 10 days of age the apical processes of the retinal pigment epithelium are abnormally elongated, by 14 days of age the retinal outer nuclear layer is reduced in thickness and contains pyknotic nuclei and the photoreceptor outer segments are disorganized and shortened. By 3 weeks of age the photoreceptor layer is reduced to one to two layers of cells and the outer segments are not visible. Both dark and light adapted flash electroretinograms show reduced amplitude responses as early as 14 days of age and this worsens progressively to near zero by 26 days of age. Male infertility is associated with decreased weight of the testes and epididymides and azoospermia as early as 6 weeks of age with severe degradation of spermatogenesis. Progressive leukoencephalopathy is also found, with vacuoles in the white matter tracts and cerebellum ..... For more information please see the full phenotype on the strain data sheet | ||

| 003711 | CAST.B6-Tubtub/Jng | Cryopreserved - Ready for recovery |
| Mice homozygous for the tubby spontaneous mutation experience maturity-onset obesity. Homozygous mutant mice are recognizable by increased body weight at 3 to 4 months in males and at 4 to 6 months in females. Both sexes are fertile. The increased weight is composed of excess adipose tissue. Blood glucose is normal, but plasma insulin is increased prior to obvious signs of obesity and may rise to 20 times normal by 6 months on the C57BL/6 background. Despite elevated plasma total cholesterol, triglycerides, and high-density lipoprotein cholesterol, homozygous mutant mice do not exhibit atherosclerotic fatty streak blood vessel lesions. Tubby mutant mice also exhibit retinal degeneration, initially believed due to the presence of another mutation which was called rd5, but since demonstrated to be a pleiotropic effect of the Tubtub mutation (Ohlemiller et al., 1997); the retinal phenotype is moderated by a QTL on Chromosome 11 (Ikeda et al., 2002). .....

| 000813 | CBA/J-Atp7aMo-pew/J | Cryopreserved - Ready for recovery |
| The Atp7 genes encode Cu2+ ATPases. Atp7a is the mouse ortholog of the human ATP7A gene, which is mutated in children with Menke's syndrome. The range of defects in both Menke's syndrome and in mice having mutations of Atp7a--the mottled series of mutants--are due to deficiencies in a number of copper-requiring enzymes, in turn attributed to an intracellular copper transport defect. Thus, it is likely that the Atp7a gene product functions as a copper transport protein. (For brief review and references, see Levinson et al., 1994.) Atp7aMo-pew, the mottled-pewter mutation, has the mildest effect of the known mutations at this locus. The sole phenotype noted in hemizygous males and homozygous females is their pale, silvery gray coat color. The coats of affected mice of both sexes are initially agouti; males become pewter by about 4 weeks and females at 5-6 weeks of age. Heterozygous females have normal, agouti coats throug ..... | ||

| These mice contain a mutation designed to replace gene function of the endogenous mouse Ush1c gene with the human USH1C function. They also contain a mutation (216G->A) designed to retain the endogenous mouse Ush1c sequence. Mice with this mutation carry the same truncated USH1C mRNA transcript and splicing defect as found in the cochleae and retinas of Usher 1C patients. Mice homozygous for Ush1c216A are viable, fertile, and exhibit behavioral characteristics of deaf mice; they are hyperactive, display circling and head tossing behavior, and do not have a Preyer reflex. They also develop retinal degeneration, as evident by absent auditory-evoked brainstem responses and progressive loss of rod photoreceptors, providing a novel resource to study the disease mechanism and the development of therapies. | ||

| Mice homozygous for the targeted mutation develop to term but show growth retardation that is most pronounced by three weeks of age. The majority of mutant mice die early in life, often within the first month. Survivors continue to show lower than average weight and increased mortality. Mammary gland epithelial duct development is normal in virgin mutant mice. Mutant females that survive to adulthood are fertile, but mammary glands of pregnant mice show a dramatic impairment in the expansion of alveolar lobes and mice are unable to lactate. Steroid hormone levels are normal, and there is no apparent defect in estrogen receptor number, suggesting that cyclin D1 deficiency has an effect on the target tissue directly. Mutant mice demonstrate a neurological abnormality evidenced by limb retraction when lifted by their tails.

Homozygous mutant mice display abnormal proteolipid storage by lysosomes termed neuronal ceroid lipofuscinosis. Mice also develop progressive retinal degeneration at an early age. Affected neuronal lysosomes show abnormal morphology. Severe cerebral gliosis and Wallerian degeneration of long neuronal tracts occur late in the disease and account for the motor neuron abnormalities and eventual paralysis. Homozygotes live to approximately 9 months of age. | ||
| 003148 | STOCK chky/J | Cryopreserved - Ready for recovery |
| Mice homozygous for the chick yellow mutation on an albino background have a pale yellow coat color evident by approximately 10 days of age when the first coat of hair comes in. Cataracts, lens extrusion, and retinal degeneration develop. Independent of the chick yellow mutation, mice of this background, which is an inbred of an ICR outbred population, may develop polydipsia with age. | ||
| 000279 | STOCK gr +/+ Ap3d1mh/J | Cryopreserved - Ready for recovery |
| Mice homozygous for the mocha spontaneous mutation (Ap3d1mh) have increased perinatal mortality. They are recognizable at birth by the absence of visible pigment in the eyes, which darken to deep red in adults. The hairs have considerably smaller and fewer melanin granules than normal. Behavior is abnormal, characterized by hyperactivity, tilted heads, and in some the inability to swim. All homozygotes show degenerative changes in the organ of Corti, stria vascularis, and spiral ganglion, and most show abnormalities of the otoliths in the saccule and utricle. This degeneration can be lessened by the administration of supplemental manganese or, to a lesser degree, zinc to the dam during pregnancy. Evoked auditory brainstem responses appear normal in young homozygotes, but decrease with age coincident with the cochlear degeneration with no response detected after six months of age. At three months of age, mice homozygous for the Ap3d1mh allele have si ..... For more information please see the full phenotype on the strain data sheet | ||

| 004770 | SW.B6-Soab/J | Cryopreserved - Ready for recovery |
| 002023 | SWR.M-Emv21 Emv22/J | Cryopreserved - Ready for recovery |
| This strain carries a pair of linked retroviral insertions that occurred simultaneously on Chr 18 in a MEV substrain related to MEV/1Ty. Homozygosity for one of the insertions causes a juvenile lethal wasting condition that results in death at approximately 16 days of age. The proviruses rarely recombine; during development of this incipient congenic strain, a mouse was never found to have Emv21 in the absence of Emv22. There is no evidence that either of these viruses causes germline or somatic infection resulting in integration of new germline copies. (brs per personal communication from B. Taylor) | ||
| 000939 | SWR/J-Clcn1adr-mto/J | Cryopreserved - Ready for recovery |
| Mice homozygous for the myotonia spontaneous mutations exhibit classical myotonia similar to that described in human myotonic diseases. Homozygotes are recognizable at 2 weeks of age or earlier by prolonged, stiff extension postures of the limbs when the cage is shaken or the mouse is dropped from about 10 cm. This behavior persists throughout life. When undisturbed, affected animals walk almost normally, although somewhat stiffly. They grow more slowly and weigh about 40% less than controls in adulthood. Electromyographic studies revealed changes characteristic of myotonia. These discharges do not originate in peripheral nerves, and there is no evidence of muscle fiber necrosis. | ||
| 013126 | B6.129-Accn1tm1Wsh/J | Under Development - Now Accepting Orders |
| Homozygous Accn1 (amiloride-sensitive cation channel 1, neuronal (degenerin)) targeted mutation mice display subtle alterations in mechanoreceptor and spiral ganglion function, and are more sensitive to light-induced retinal degeneration. Transcripts and protein are missing for both spliced forms of the gene, as determined by Western and Northern blot analysis of mouse brain. Homozygous mice show a reduced reproductive capacity that is reportedly 25% that of wildtype mice. This strain may be helpful in studies of touch sensation. | ||
| 017009 | B6.129X1-Nfe2l2tm1Ywk/J | Under Development - Now Accepting Orders |
| In this Nrf2 knockout strain, a β-galactosidase (lacZ) reporter followed by a neomycin resistance (neo) cassette replaces exon 5 and part of exon 4 encoding the nuclear factor, erythroid derived 2, like 2 (Nfe2l2) gene, abolishing gene function. Homozygotes are viable, fertile, and normal in size. NRF2, a member of the "cap 'n' collar" (CNC) subfamily of the basic region-leucine zipper transcription factors, is a regulator of endogenous antioxidant protection, microglial function, and chronic neuroinflammation. Inactivation of the CNC, DNA binding, and leucine zipper domains in Nrf2-/- mice results in age-related macular degeneration (AMD)-like retinal pathology, spontaneous choroidal neovascularization (CNV), increased sensitivity to toxins, impaired adipogenesis, abnormal mitochondria, and an increase in proinflammatory gene expression in microglia and astrocytes. These mice may be useful for studying oxidative stress in the pathogenesis ..... For more information please see the full phenotype on the strain data sheet | ||
| 014173 | STOCK Tyrc-2J Omptm1.1(COP4*/EYFP)Tboz/J | Under Development - Now Accepting Orders |
| These OMP-ChR2-YFP (OCY-58) mice express a ChR2(H134R)-EYFP fusion gene from the olfactory marker protein locus (Omp). Mice that are homozygous for the targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. ChR2(H134R)-EYFP is expressed in all mature olfactory sensory neurons, rendering them light sensitive. Light directed at the olfactory epithelium or the glomeruli can elicit activity in mitral/tufted (M/T) cells of the olfactory bulb and can drive odor guided behavior. These mutant mice thus allow precise, timed delivery of stimuli input to the olfactory system. The Donating Investigator reports that this this targeted mutation creates a null allele. Due to possible olfactory deficits, analysis should be performed in heterozygous mice. The Donating Investigator recommends keeping the strain on the albino B6 background to avoid possible interference by pigmented melanocytes.
