A statistically significantly higher frequency of p53 mutations was found in breast tumors from carriers of BRCA1 mutations than from noncarriers, which adds to the accumulating evidence that loss of p53 function is an important step in the molecular pathogenesis of BRCA1 mutation-associated breast tumors.
