Trp53 mice carrying gain of function point mutations do develop a broader range of cancers that is closer to human cancers with TP53 mutations and TP53-deficient hamsters with one major exception in that they do not develop myeloid leukemias, which are common in TP53 mutants (especially homozygous mutant) hamsters and in human myeloid leukemia patients. This evidence concerns the gene TP53 and cancer.
