As part of a panel screening approach in breast cancer cases ascertained through familial cancer clinics in Australia, we evaluated the incidence of the BRCA2 variant rs11571833 in 2634 cases and 1996 controls, which had previously been filtered to remove cases with pathogenic mutations in BRCA1 and BRCA2, including the BRCA2 c.6503delTT pathogenic mutation linked to rs11571833 (seen in one control). Here, BRCA1 is linked to hereditary cancer.
