Two recent large case control studies CARRIERS in the USA3 and BRIDGES mainly in Europe4 identified six additional genes with actionable increased risks of breast cancer with ORs of around twofold to threefold (RAD51C, RAD51D, BARD1, ATM, CHEK2) and one at fourfold to fivefold (PALB2). This evidence concerns the gene BARD1 and breast carcinoma.
