Summary (CIViC Variant)
While loss-of-function events in TP53 are very common in cancer, the R273 variants seem not only to result in loss of tumor-suppression, but also act as a gain-of-function mutation that can promote tumorigenesis in mouse models. This mutant is also more responsive to treatment with doxorubicin than its wild-type counterparts. While the prognostic impact of individual TP53 mutations is influenced by the cohort being studied, it has been suggested that the R273 mutants have been correlated with worse overall survival in breast cancer patients when compared to wild-type.
