Twenty patients harbored a pathogenic variant in a gene associated with a high risk of developing the disease (BRCA1, BRCA2, PALB2, TP53), twenty patients carried a moderate risk variant (CHEK2, ATM, BRIP1, RAD51C, PMS2), eighteen patients had a pathogenic variant in a gene with low/undetermined correlation with BC, and forty-seven patients had no detectable variation. The gene discussed is BRCA1; the disease is breast cancer.
