Patient clinical features of BC and OC and cancer family history were collected and compared to the patient genetic profile.A total of 255 women were analyzed, 57 of whom had a pathogenic mutation in BRCA1/2 genes, and 17 carried pathogenic mutations in other genes, such as PALB2, ATM, BRIP1, RAD51D, MSH6, PPM1D, RECQL4, ERCC3, TSC2, SLX4 and other Fanconi anemia genes.Patients with a pathogenic mutation in genes other than BRCA1 and BRCA2 showed no significant difference from the BRCA1/2-mutated carriers with respect to age at diagnosis and clinical features, suggesting that mutations in other genes could pose a high risk of cancer development.These patients had a much higher percentage of bilateral breast cancer (BBC) and a lower rate of OC than BRCA-mutated patients and patients with no pathogenic mutations: as a consequence, the surveillance protocol should be customized to the patient genetic characteristics.
