The lifetime risk of PDAC is about 1% for BRCA1 and 4.9% for BRCA2 PV/LPVs carriers [30], and studies by the Breast Cancer Linkage Consortium reported a 2.3-fold and 3.5-fold increased risk of PDAC in carriers of BRCA1- and BRCA2-altered variants, respectively [14]. Here, BRCA2 is linked to breast carcinoma.
