Abstract Advances in the study of BRCA1 and BRCA2 gene functions have relied on the development of animal models for seeking to explore further what we have learned from the human disease. Specifically, mouse models of a 'triple-negative' breast cancer (utilizing conditional knockout of BRCA1 and p53 in the breast), of an endometrioid ovarian cancer (based on oncogenic kras and loss of function of pten), and of anatomic and functional consequences of BRCA1 mutations in granulosa cells, have led to further inquiry into the pathogenesis and therapeutic consequences of genetic alterations. A striking susceptibility of these murine malignancies to platinum drugs has emerged, providing further confidence in their relevance to the human disease. In addition to these models, the pathogenesis of high-grade serous disease derived from risk-reducing surgeries in mutation carriers has pointed to a role of mutations in p53 commonly encountered in tubal intraepithelial carcinomas.
