Breast cancer was diagnosed in most of our cases (179/205; 87.3%), of which we identified genetic variants in 51 cases, representing 28.5% of the breast cancer patients: twelve BRCA2 (6.70%), eight CHEK2 (4.47%), eight BRCA1 (4.47%), seven ATM (3.91%), three PALB2 (1.68%), and 2-2 variants in BARD1, FANCI and RAD51C genes (1.12%), and 1-1 variant in APC, BLM, CDH1, ERCC2, KIT, MSH6,, PMS2, RAD50, RAD51B, and RET genes (0.56%). This evidence concerns the gene BLM and breast cancer.
