摘要
Patients with germline mutations in BRCA1 or BRCA2 genes are predisposed to breast cancer. The BRCA1-associated breast cancers have distinct morphology, being more often medullary-like, triple negative and showing a 'basal' phenotype. On the other hand, BRCA2 and BRCAX cancers are a heterogeneous group without a specific phenotype. When incorporated into risk assessment models, pathology data improves prediction of carrier status. The role of BRCA1 and BRCA2 in DNA repair is being exploited to develop novel therapies, for example, using the poly-ADP-ribose polymerase inhibitors. A number of low-to-moderate-penetrant genes/loci have also been identified, but their role and contribution in breast cancer development is still under investigation.
