N normal phenotype
endocrine/exocrine glands
• mutant adrenal glands are hypoplastic ad display a severe loss at the level of the glucocorticoid-producing fasciculata layer
• homozygotes exhibit only a few remaining POMC (ACTH)-positive pituitary cells relative to wild-type and heterozygous control mice

homeostasis/metabolism
• after a 24-hr fast, homozygotes display a significantly greater fasting-induced hypoglycemia than wild-type and heterozygous control mice
• fasting-induced hypoglycemia can be associated with seizures or death during fasting
• homozygotes exhibit significantly higher basal plasma glucose levels relative to wild-type or heterozygous control mice
• unlike wild-type and heterozygous control mice, homozygotes exhibit no detectable plasma corticosterone levels
• homozygotes display very low, though still detectable, plasma ACTH levels, relative to wild-type and heterozygous control mice

nervous system
• homozygotes exhibit only a few remaining POMC (ACTH)-positive pituitary cells relative to wild-type and heterozygous control mice

pigmentation
• homozygotes show a yellow ventrum pigmentation instead of the light gray pigmentation observed in wild-type or heterozygous control mice
• homozygotes display deficient pigmentation

reproductive system
N
• homozygotes are fertile, indicating a functional pituitary gonadal axis

integument
• homozygotes show a yellow ventrum pigmentation instead of the light gray pigmentation observed in wild-type or heterozygous control mice

growth/size/body
• homozygotes display increased water retention in their fur
