mortality/aging
• 26% of heterozygous mice were found dead before normal life span with evidence of widespread infections

neoplasm
• in untreated mice, the incidence of spontaneous tumors of various types was 53%
• 10 weeks after NMBA treatment, all heterozygous mice exhibited tumors in various tissues, especially the gastrointestinal tract including the forestomach and squamocolumnar juction; the incidence of tumors in control mice was 25% (J:61946)
• 78% of mice exhibit large sebaceous tumors after a single dose of NMBA, especially in the gastrointestinal tract (J:71303)
• mutants develop preneoplastic lesions of the uterus more frequently than wild-type after multiple doses of benzol[a]pyrene (B[a]P), however develop similar levels of forestomach and lung tumors (J:110096)

hematopoietic system
• granulocyte numbers are 2-6% of total blood lymphocytes; controls granulocyte numbers are 15% of total

immune system
• granulocyte numbers are 2-6% of total blood lymphocytes; controls granulocyte numbers are 15% of total
• mice exhibit evidence of widespread infections and abcesses

homeostasis/metabolism
• 10 weeks after NMBA treatment, all heterozygous mice exhibited tumors in various tissues, especially the gastrointestinal tract including the forestomach and squamocolumnar juction; the incidence of tumors in control mice was 25% (J:61946)
• 78% of mice exhibit large sebaceous tumors after a single dose of NMBA, especially in the gastrointestinal tract (J:71303)
• mutants develop preneoplastic lesions of the uterus more frequently than wild-type after multiple doses of benzol[a]pyrene (B[a]P), however develop similar levels of forestomach and lung tumors (J:110096)

integument
• spontaneous alopecia areata and hair bulb cell apoptosis are greatly accelerated in mutants compared to wild-type
