Furthermore, we evaluated whether carrying a rare deleterious or predicted deleterious variant (D-PDV) (i.e., loss-of-function or missense variant with a predicted deleterious effect, phred CADD score ≥ 20 [14]) in 113 DNA repair genes (other than BRCA1/2) previously selected [15,16] modifies the association between mammography screening exposures and BC risk. Here, BRCA1 is linked to breast cancer.
