mortality/aging
• mice become moribound and die from anemia and intestinal obstruction at a mean age of 82 days

neoplasm
• mice exhibit accelerated intestinal tumorigenesis compared to single ApcMin heterozygous mice, with a large increase in number of small and large bowel adenomas that develop
• an average of 333 adenomas are seen in 10 mutants at 47-78 days of age compared to a mean of 48 adenomas in single ApcMin heterozygotes

digestive/alimentary system
