Hereditary breast and ovarian cancer (HBOC) is a syndrome defined by an increased risk of developing breast and/or ovarian cancer most commonly due to germline disease-causing variants in the BRCA1 and BRCA2 genes, but also other causative genes such as PALB2, ATM and CHEK2. As genetic testing becomes more prevalent and new clinical data emerge, updates of national guidelines are required to incorporate these advances in our knowledge. The aim of this work is to review the guidelines for HBOC genetic testing and clinical surveillance across European countries, mostly affiliated to the European Reference Network (ERN) for Genetic Tumor Risk Syndroms (GENTURIS). Young onset breast cancer (BC), triple negative phenotype, or bilateral BC are considered as criteria for genetic testing in all, with differences in age limits. Testing of invasive epithelial non-mucinous ovarian cancer is also …
