N normal phenotype
endocrine/exocrine glands
• a slight decrease in hematological malignancies (primarily T cell lymphomas) is seen compared to Trp53tm1Tyj homozygotes (50% compared to 66%)

mortality/aging
• mean life span is 4.5 months
• a slight decrease is seen in the number of females born

neoplasm
• 57% have multiple tumors, significantly more than in Trp53tm1Tyj homozygotes (32%)
• a slight decrease in hematological malignancies (primarily T cell lymphomas) is seen compared to Trp53tm1Tyj homozygotes (50% compared to 66%)
• carcinomas are seen in 16% of mice, with most carcinomas showing signs of invasion, metastasis, or other features of advanced human carcinomas
• most carcinomas are derived from epithelial cells
• the incidence of hemangiosarcomas is increased to 62% compared to 32% in Trp53tm1Tyj homozygotes and these tumors are highly aggressive
