BRCA2 and breast carcinoma: A large number of genes can now be screened in single assay, at considerably reduced cost, thus providing opportunities for the large number of women who will undergo gene panel testing, including those who have never undergone testing and those previously not found to carry mutations in BRCA1 and BRCA2. By increasing the diagnostic yield through the analysis of more breast cancer susceptibility genes, gene panel testing provides more women and their families the opportunity to receive personalised risk assessment and risk management.
