Figure 3 and online supplemental tables S3 and S4 show the age-specific distributions of ER-negative tumours and TN tumours among ER-negative tumours used in the models for PALB2, ATM, CHEK2, BARD1, RAD51C and RAD51D PV carriers based on the BRIDGES data.19BARD1, RAD51C and RAD51D PV carriers predominantly develop ER-negative BCs, and the proportions decrease with increasing age. Here, CHEK2 is linked to neoplasm.
