| 000648 | AKR/J | Level 2 |
| Originally inbred at the Rockefeller Institute, AKR mice are widely used in cancer research for their high leukemia incidence (60-90%) and in immunology as a source of the Thy1.1 (theta AKR) antigen. AKR/J mice are viremic from birth, and express the ecotropic retrovirus AKV in all tissues. The hair interior defect (hid) mutation, a strain characteristic of AKR mice, causes alterations in hair development that is only evident microscopically. Adrenocortical lipid depletion (ald) in AKR mice is caused by a mutation in sterol O-acyltransferase 1 (Soat1), and leads to a truncated SOAT1 protein. AKR/J mice are relatively resistant to aortic lesion formation on a semi-synthetic high fat diet and are hyporesponsive to diets containing high levels of fat and cholesterol. | ||
| 002468 | KK.Cg-Ay/J | Level 2 |
| Ay and other mutations at the a locus conferring a completely yellow coat color are dominant to all a alleles that produce a darker coat. Hair pigment of Ay heterozygotes is yellow, but eyes are black. Heterozygotes usually become obese and infertile within a few months after birth. Increased adipose tissue mass is due to fat cell hypertrophy, and it has been hypothesized that the obesity results from the observed reduction in hypothalamic norepinephrine and dopamine. Heterozygotes are more susceptible to several kinds of tumors than are normal mice, possibly due, at least in part, to a general increase in cell proliferation that also manifests as a slight increase in lean body mass and skeletal length. Further spleen cells from heterozygotes cause a significantly lower graft vs. host reaction. Mice homozygous for the yellow spontaneous mutation (Ay) die before implantation, or shortly thereafter.

| 002019 | NU/J | Level 3 |
| The two main defects of mice homozygous for the nude spontaneous mutation (Foxn1nu, formerly Hfh11nu) are abnormal hair growth and defective development of the thymic epithelium. Although the mice appear hairless, they are born with functional but faulty hair growth follicles. Hair growth cycles and patterns are evident especially in pigmented mice but the faulty follicles do not allow the hair to properly erupt. Homozygous pups can be identified as young as 24 hours by their lack of whiskers or poorly developed, crinkled whiskers. Nude mice are also athymic caused by a developmental failure of the thymic anlage. Consequently, homozygous nude mice lack T cells and suffer from a lack of cell-mediated immunity. However there is not a defect in T-cell precursors, and under the right conditions some functional mature T cells can be found especially in adult mice. Because of a defect in helper T-cell activity, responses to thymus-dependent antigens when d

| 006941 | B6.129S7-B4galt1tm1Shur/J | Repository- Live |
| Mice that are heterozygous for the targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. Ninety percent of homozygotes die soon after birth or within two to three weeks of birth. Surviving homozygotes are initially smaller than wild-type or heterozygotes and exhibit abnormal skin and coat, but assume a normal growth rate and appearance at three to four weeks of age. No gene product (mRNA) is detected by RT-PCR analysis of homozygous tissues. Neither the long or short isoform is expressed. Beta 1,4-galactosyltransferase enzyme activity is undetectable except for residual activity in brain and testis. Galactose residues are absent from testis. Heterozygotes have an intermediate enzyme activity level. Surviving homozygotes exhibit puffy faces (hypothyroid myxedema), thin skin, decreased density of hair follicles, reduction in subdermal adipose tissue, delayed spermatogenesis and incomplete lung development. Histological an

| 008115 | B6.129X1-Pomctm2Ute/J | Repository- Live |
| Mice that are heterozygous for the targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. 60 to 75% of homozygotes die perinatally. Surviving homozygotes have decreased fertility and homozygous females produce milk that does not allow pups to survive past 14 days of age. No serum adrenocorticotropic hormone (ACTH) or corticosterone was detected by radioimmunoassay (RIA) of homozygotes. Serum epinephrine and aldosterone levels are reduced. Although homozygotes are born with adrenal glands or normal size, adrenal glands fail to grow postnatally and become almost undetectable with age. By 3 months of age, mice homozygous for the mutation are twice the weight of wildtype controls and increased serum leptin levels. Heterozygotes exhibit elevated serum leptin levels, but not increased weight and reduced levels of serum adrenocorticotropic hormone (ACTH), corticosterone, and aldosterone levels. Both heterozygotes and homozygote

| 000021 | B6.Cg-Ay/J | Repository- Live |
| Mice homozygous for the yellow spontaneous mutation (Ay) die before implantation or shortly thereafter. The time of death and type of abnormality is, in part, determined by the genetic background on which the mutation is placed. Hair pigment in heterozygous mice is yellow, but eyes are black. Heterozygotes usually become obese and infertile after the first few months. Increased adipose tissue mass is due to fat-cell hypertrophy. It has been hypothesized that the obesity results from the observed reduction in hypothalamic norepinephrine and dopamine levels. Insulin resistance and hyperglycemia follow development of hyperinsulinemia in early adulthood, although the degree is less severe than on the KK/UpJ genetic background (Stock No. 002468). Heterozygotes are also more susceptible to several kinds of tumors than normal mice, and their spleen cells cause a significantly lower graft vs. host reaction. The level of

| 007005 | 129S-Scg5tm1Led/J | Repository-Cryopreserved |
| The following text reflects the phenotype reported by the donating investigator on a "129Sv" genetic background (probably "Taconic Sv129" (129S6/SvEvJ)). While heterozygotes are viable and fertile, mice homozygous for this mutation (7B2-null) die in prepubertal or pubertal ages (5 weeks) with severe cardio-respiratory failure, convulsions, and hypothermia. No transcripts are detected in brain tissue from the targeted gene. 7B2 null mice are unable to make an active form of prohormone convertase 2 (PC2) and have high circulating corticosterone. Homozygotes on the 129S genetic background exhibit Cushing's-like disease pathologies of liver, pancreas, and pituitary; including pituitary-dependent hyperadrenocorticosteronism, severe hypoglycemia, hyperproinsulinemia, adrenal hypertrophy, pituitary hypotrophy, and altered islet cell morphology. 7B2-null mice develop the disease from intermediate lobe ACTH hypersecretion (rather than from pituitary adenomas). Other abnormalities include thinni

| 003114 | B6.129S2-Crhtm1Maj/J | Repository-Cryopreserved |
| Mice homozygous for the Crhtm1Maj targeted mutation are viable and fertile. Pups born to homozygous mothers must be supplemented with corticosterone in the drinking water from day 12 of gestation until weaning. Homozygous mice have reduced adrenocortical secretion following stress. They may be susceptible to complications from hypoglycemia when fasting. Heterozygous mice are phenotypically indistinguishable from normal wildtype siblings. | ||
| 000017 | B6.C3Fe-Avy/J | Repository-Cryopreserved |
| Homozygous (Avy/Avy) and heterozygotes (Avy/A and Avy/a) show considerable variation in appearance, ranging from clear yellow, to mottling with dark patches, to a completely agouti-like coat. The variation is strongly influenced by the agouti-locus genotype and strain genome of the dam. Homozygotes and heterozygotes tend to become obese, and the degree of obesity is correlated with the amount of yellow in the coat. Avy resembles Ay in causing greater tumor susceptibility and lower graft vs. host reactivity and higher hepatic malic enzyme activity. Homozygotes have a reduced humoral response to tetanus toxoid and decreased rates of carbon clearance as well as impaired mononuclear phagocyte function. The greater tumor susceptibility as well as several altered immune responses occur in Avy/a mice of mottled phenotype but not in those of agouti phenotype. | ||
| 002783 | B6;129S2-Crhtm1Maj/J | Repository-Cryopreserved |
| Mice homozygous for the Crhtm1Maj targeted mutation are viable and fertile. Pups born to homozygous mothers must be supplemented with corticosterone in the drinking water (10-30ug/ml) from day 12 of gestation until weaning. Homozygous mutant mice have reduced adrenocortical secretion following stress. They may be susceptible to complications from hypoglycemia when fasting. Heterozygous mice are phenotypically indistinguishable from wildtype siblings. | ||
| 000504 | B6EiC3Sn a/A-Cacnb4lh/J | Repository-Cryopreserved |
| Mice homozygous for the lethargic spontaneous mutation (Cacnb4lh) are first recognizable at 15 days by their lethargic behavior with gait instability and occasional seizures. The seizures resemble human petit mal seizures. No pathological changes were found in the CNS or in skeletal muscles, but peripheral motor nerves show reduced conduction velocity and prolonged distal latency. There is early thymic involution at 3 to 4 weeks in Cacnb4lh homozygotes, accompanied by decreased lymphocyte count, decreased cell-mediated immunity, and increased levels of serum IgG1. The defects in the immune system tend to disappear by 2 months of age in mice that survive. In addition to neurological and immunological defects, homozygous lethargic mice show pituitary-adrenal hypercorticism. Homozygotes are smaller and weaker than their normal littermates and often die before 2 months old. Survivors of both sexes may breed, but their reproductivity is low. | ||

| 001595 | DW/J-Acdacd/J | Repository-Cryopreserved |
| acd/acd homozygotes can be distinguished from their wildtype (?/+) littermates by darkened pigmentation, short, curly vibrissae, smaller overall size, and abnormal pelage. Hair growth is retarded and lacks zigzag and guard hairs producing a sparse coat. There is heavy pigmentation in the nose, ears, body, feet and tail, and foci of melanin are also found in the skin and lymph nodes. Tail kinks or polydactyly of the hind feet are sometimes found and external genitalia are underdeveloped. It is rare for homozygotes to breed. Hydronephrosis is sometimes found in post-wean aged homozygotes resulting from focal hypertrophy of ureteral epithelium which causes ureteral blockage. The adrenals are abnormal in both males and females. Although the size of the medullary cells is normal, the cortical cells and nuclei are much larger than normal with nuclear inclusions and many mitochondria in the cytoplasm. These mitochondria have tubular cristae and cholesterol ester droplets, whic

| 003118 | STOCK Es1e Foxn1nu/J | Repository-Cryopreserved |
| Mice homozygous for Es1e are viable and fertile and exhibit no apparent defect. Es1e was discovered in a screen of progeny of triethylenemelamine (TEM) treated male mice for mutations at specific loci, but appears to have pre-existed in the male. The screen employed analysis of blood and kidney homogenates by "standard starch gel electrophoresis techniques" and focused on enzymes known to differ in electrophoretic mobility between the parental strains (DBA/2J and C57BL/6J). Es1e was initially thought to be a null allele, but characterization of homozygous F2 mice demonstrated presence of a faint band migrating between those of the parental strains, which was not perceived in the presence of either parental band. Thus, Es1e was shown to be a hypomorphic electrophoretic variant (Soares 1979). The two main defects of mice homozygous for the nude spontaneous mutation (Foxn1nu, formerly Hfh11<
