In one series of patients, with a family history of breast cancer but no mutation seen in BRCA 1 or 2, a 42-gene panel assay found additional findings in 15 of 141 patients (11%), most of whom had breast cancer, with germline mutations/variants seen in ATM, BLM, CDH1, CDKN2A, MUTYH, MLH1, NBN, PRSS1 and SLX4 genes [9]. The gene discussed is CDKN2A; the disease is breast cancer.
