| 002448 | 129S1/SvImJ | Level 2 |
| Historically, the 129 inbred mice are known for the high incidence of spontaneous testicular teratomas, though the incidence differs between substrains.(1-3% in 129 parental substrains; 30% in teratoma substrains.) More recently, 129 mice are widely used in the production of targeted mutations due to the availability of multiple embryonic stem cell lines derived from them. There is major genetic variation within the 129 "family", which has led to an update of the nomenclature and a division of the substrains into three major groups: parental substrains (129P), steel substrains (129S) and "teratoma" substrains (129T). Investigators using 129 substrains for targeted mutagenesis should be careful in the selection of the appropriate 129 substrain to match the embryonic stem cell line. For a complete history of the numerous 129 substrains, see Simpson, et al., 1997.

| 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. | ||

| 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. | ||

| 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 .....

| 009358 | B6;129S2-Lats1tm1Tx/J | Repository- Live |
| Homozygous animals exhibit a lack of mammary gland development, infertility and growth retardation. Accompanying these defects are hyperplastic changes in the pituitary and decreased serum hormone levels. The reproductive hormone defects of homozygotes are reminiscent of isolated luteinizing hormone (LH)-hypogonadotropic hypogonadism and corpus luteum insufficiency in humans. Furthermore, Homozygous mice develop soft tissue sarcomas (some by 4-10 months of age) and ovarian stromal cell tumors (by 3 months of age) and are highly sensitive to carcinogenic treatments. Data demonstrates a role for this gene in mammalian tumorigenesis and specific endocrine dysfunction. | ||
| 013591 | FVB-Tg(C3-1-TAg)cJeg/JegJ | Repository- Live |
| Male transgenic mice develop prostatic hyperplasia in early life that progresses to adenoma or adenocarcinoma in about half of the animals which survive longer 7 months of age. Female animals generally develop mammary intraepithelial neoplasia with similarities to DCIS by 3 months of age with subsequent development of mammary adenocarcinoma by 6 months of age in 100% of the animals. About 10 - 15% of female mice develop lung metastases, although lung metastases from prostate cancer is extremely rare. Bone metastases have not been observed. The phenotype for this transgene has been most extensively studied in the FVB/N background. | ||

| 002105 | NZO/HlLtJ | Repository- Live |
| NZO mice of both sexes exhibit high birth weights and are significantly heavier at weaning age, Severe obesity (including both visceral and subcuatneous fat depots) develops even when mice are maintained on a standard diet containing 4.5% fat. Both males and females of the NZO/Hl substrain exhibit impaired glucose tolerance (IGT), but subsequent type 2 maturity onset (NIDDM) diabetes development is limited to males, with a phenotype penetrance of 50% or less. NZO/Hl mice also show anti-insulin receptor antibodies, a defect in leptin transport, and hypertension. The genetic lesion appears to be within the islets of Langerhans as transfer of pancreatic islets from normal mice returns body weights and blood glucose levels to within normal range. Ovarian granulosa cell tumors, lymphomas, duodenal, and lung tumors have also been noted to occur in NZO mice at an elevated frequency. F1 hybrids of NON/ShiLt and NZO/Hl provide a new model of obesity-induced diabetes. Male (NON/ShiLt x NZO/Hl)F1 ..... For more information please see the full phenotype on the strain data sheet | ||

| 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 .....

| Mice homozygous for the Mostm1Ev targeted mutation are viable. Homozygous males are fertile; the littersize of homozygous females is markedly lower than that of wild type or heterozygous mice. Eggs lacking Mos undergo spontaneous parthenogenetic activation (extrusion of the second polar body and pronucleus formation without fertilization). Ovarian cysts develop in homozygous females as young as one month. Some of the ovarian cysts consist of several tissue types, including possible thyroid tissue, similar to about 10% of all benign cystic teratomas in human beings. | ||

| 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 | ||

| 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 | ||

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.

| 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 .....

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.

| 001079 | SWXJ9/BmJ | Cryopreserved - Ready for recovery |
| SWXJ9 female mice develop ovarian granulosa cell carcinomas with an incidence of approximately 12% and a latency of 4-6 weeks. Tumor incidence can be increased to approximately 40% by treatment with dehydroepiandrosterone (DHEA) or testosterone immediately after weaning. Treatment with estradiol during this period completely suppresses tumorigenesis. Neoplasias are first observed as hemorrhagic follicles in which the antrum is blood-filled and lined with irregular masses of proliferating granulosa cells. By 6-10 weeks of age, the primary tumor encompasses the entire ovary. Metastases to lung, renal node, and liver are common by 6 to 9 months of age, with other sites occasionally affected. Susceptibility to granulosa cell carcinomas is controlled by a small number of genes, including a major susceptibility locus on Chromosome 4 and a major modifier locus on the X chromosome. | ||
