TP53 and breast cancer: The identification of genes that have synthetic lethality with mutant TP53 is a promising approach in this regard, since TP53 mutations occur in approximately 40% percent of all breast cancers, with the highest frequency found in the basal-like (80%) and HER-2-enriched (72%) subtypes of TNBC, and the lowest found in the Luminal A (12%) and Luminal B (29%) subtypes [3, 4].
