phenotype observed in females
phenotype observed in males
N normal phenotype
mortality/aging
• half the expected number of homozygotes survive until weaning due to decreased birth rates and cannibalism of small homozygote pups
• about 18% of E10-E13.5 embryos are homozygotes instead of the expected 25%

growth/size/body
• the weight of mutant mice is reduced about 40% with low body weight persisting throughout the lifespan of the mice

digestive/alimentary system
• thickness of intestines are reduced by about a third
• the number of cells in colon crypts are reduced by about a third
• intestines are smaller in length

endocrine/exocrine glands
• the number of cells in colon crypts are reduced by about a third
• testis weight is decreased by 25% compared to controls

homeostasis/metabolism
• embryonic fibroblasts are insensitive to the anti-apoptotic effects of IGF-1

nervous system
• brain weight is decreased by 25% compared to controls

reproductive system
• testis weight is decreased by 25% compared to controls

skeleton
• hip bones are smaller than controls
• vertebrae are smaller than controls

N normal phenotype
mortality/aging
• nearly half of all pups born die within the first 25 postnatal days
• some intrauterine loss of pups and occasional resorbing is observed between E12.5 and E17.5

cardiovascular system
N
• hearts function normally and isoproterenol treatment fails to induce cardiac hypertrophy as it does in wild-type mice
• cardiac myocytes exhibit an increased number of mitochondria and abnormal sarcomere structure at P10; sarcomere length is reduced while Z-bands appear broad and fuzzy
• however, structural changes are largely resolved by P65
• despite being born with normal hearts, mice have reduced trabeculation through P8
• despite being born with normal hearts, mice have thickened myocardial compact zones through P8
• at P8, mice exhibit enlarged hearts relative to their reduced body size
• however, by two months hearts are normal size
• at P8, mice exhibit thickened ventricular walls and decreased ventricular cavity size
• proliferation is elevated starting at E15.5 and is more apparent at P2

behavior/neurological
• at P10
• however, by two months mice are indistinguishable from wild-type

growth/size/body
