Moreover, most cases of inherited susceptibility to EOC are primarily related to germline mutations of BRCA1 and BRCA2, which account for 95% of hereditary ovarian cancers and have been implicated in several cellular processes, including homologous recombination (HR), chromatin remodeling, regulation of the cell cycle, transcription, cell growth and differentiation. This evidence concerns the gene BRCA1 and ovarian cancer.
