N normal phenotype
endocrine/exocrine glands
• early onset of growth of mammary gland with much more ductal growth
• premature exhaustion of ovarian function

mortality/aging
• premature exhaustion of ovarian function

reproductive system
• premature exhaustion of ovarian function
• early onset of growth of uterine glands
• by 15 month of age, the uterine glands were prematurely sclerotic and atrophic and the mammary glands showed signs of atrophy
• precocious puberty in females
• mutant females begin estrus cycling 2 days earlier than their wild-type littermates
• at 15 month of age, estrous cycling has prematurely terminated in mutant females

integument
• early onset of growth of mammary gland with much more ductal growth
