摘要: Carriers of heterozygous mutations in BRCA1 or BRCA2 are strongly predisposed to breast and ovarian cancers. Cancers arising these individuals have consistently lost the wild-type allele during tumour progression, therefore deficient function. Both proteins been implicated repair double-strand DNA breaks by homologous recombination. This functional role could be exploited treatment BRCA-deficient cancers targeting tumours with drugs that create damage highly reliant on for repair.
