N normal phenotype
mortality/aging
• homozygotes are considerably reduced in numbers at 1 day after birth
• normal survival from 1 day of age to 1 year

growth/size/body
• survivors remain smaller than controls
• emaciated appearance
• mean weight is 80% of controls in the first day after birth
• significantly reduced growth rate prior to weaning
• weight is 69% of controls at 6.5 weeks of age
• weight deficits are never recovered

behavior/neurological
• ungroomed coat
• mating behavior of males is reduced with reduced plug formation when mated to control females
• females ""plug"" less frequently when mated with wild-type males

reproductive system
• reduced uterine gland size
• development only to the antral stage
• reduced size due to reductions in the muscularis layer as well as the uterine stroma and strata basalae
• round and elongated spermatids are rare
• increased incidence of disruption but only in undescended testes
• many cells at the luminal border of the epithelium in the undescended testes are degenerating
• multinucleated giant cells are often seen in the undescended testes
• undescended testes are small
• may be unilateral or bilateral
• follicular development does not continue beyond antral stage
• reduced mating behavior
• disruption of spermatogenesis in undescended testes

endocrine/exocrine glands
• thickness of the zona reticularis is reduced
• other regions of the adrenal are not consistently altered
• adrenal cell types are normal
• thinning of the cortex with reduced numbers of lymphocytes
• reduced cellularity
• reduced uterine gland size
• development only to the antral stage
• many cells at the luminal border of the epithelium in the undescended testes are degenerating
• multinucleated giant cells are often seen in the undescended testes
• undescended testes are small
• may be unilateral or bilateral

immune system
• at 4 weeks of age but not at 6 weeks of age
• reduced proportion of early B cell progenitor cells seen at 4 weeks but not at 6 weeks of age
• decreased numbers of double positive T cells in thymus at 4 weeks of age but not a 6 weeks
• increased numbers of single positive T cells in thymus at 4 weeks of age but not a 6 weeks
• at 4 weeks of age but not at 6 weeks
• thinning of the cortex with reduced numbers of lymphocytes
• reduced cellularity
• reduced cellularity but overall spleen architecture is normal

hematopoietic system
• thinning of the cortex with reduced numbers of lymphocytes
• reduced cellularity
• at 4 weeks of age but not at 6 weeks of age
• reduced proportion of early B cell progenitor cells seen at 4 weeks but not at 6 weeks of age
• decreased numbers of double positive T cells in thymus at 4 weeks of age but not a 6 weeks
• reduced cellularity
• increased numbers of single positive T cells in thymus at 4 weeks of age but not a 6 weeks
• reduced cellularity but overall spleen architecture is normal
