A 2018 study in Colombia, aiming to describe the frequency and type of pathogenic germline mutations in breast and ovarian cancer susceptibility genes, showed that nineteen patients (22.4%) carried a harmful germline mutation in a cancer susceptibility gene: BRCA1, BRCA2, PALB2, ATM, MSH2, or PMS2. Here, BRCA1 is linked to ovarian carcinoma.
