digestive/alimentary system
• at P16 - P21 in homozygous mutants the intestines appear relatively small and gas bubbles are present within the intestines
• at P5 - P21 the small intestines from homozygous mutants appear very immature with a reduction in the number and size of villi
• at P0 the small intestines from homozygous mutants are smaller in diameter compared to wild-type mice
• at P16 - P21 the stomach in homozygous mutants is relatively small
• the small intestinal abnormalities appear to cause insufficient digestion and severe starvation atrophy

growth/size/body
• homozygous mice exhibit severe growth retardation even in the absence of competition from wild-type littermates
• at P16 - P21 abnormalities are seen in most organs excluding the brain consistent with the miniature size of the homozygous mutants with the average weight of most organs being 50% that of wild-type littermates

hematopoietic system
• at P16 the average spleen weight per body weight of homozygous mutants is 28% that of wild-type mice

homeostasis/metabolism
• primary embryonic fibroblasts from homozygous mutants are hypersensitive to UV irradiation compared to fibroblasts from wild-type mice
• UV induced DNA lesions are not removed in homozygous mutant cel

immune system
• at P16 the average spleen weight per body weight of homozygous mutants is 28% that of wild-type mice

liver/biliary system
• liver cells form homozygous mutants are much smaller than those in heterozygous mice

integument
• primary embryonic fibroblasts from homozygous mutants are hypersensitive to UV irradiation compared to fibroblasts from wild-type mice
• UV induced DNA lesions are not removed in homozygous mutant cel
