Multicenter cross-sectional screening of the BRCA gene for Chinese high hereditary risk breast cancer populations.

ABSTRACT: Due to lack of systematic reviews, BRCA, DNA Repair Associated (BRCA) mutations in the Chinese population are not completely understood. The following study investigates the prevalence and type of BRCA mutations in Chinese patients with high hereditary risk of breast cancer (BC). Patients Drwere recruited from 14 cities between October 2015 and February 2016, and were selected based on family and personal medical history. BRCA mutations were analyzed by collecting blood samples from all participants. 437 BC patients were included. A total of seventy-six (17.4%) mutation carriers were identified with no geographic difference. The mutation rate in the early-onset BC patients was lower compared to family history of breast/ovarian cancer (OC), bilateral BC, male BC, BC&OC or meeting ≥2 criteri
