Recent studies suggest a hereditary component is involve in TNBC development, especially in young patients. However, genetic spectrum remains unclear. Our purpose was to evaluate the usefulness of multigene panel testing in triple negative patients respect overall breast cancer cases as well as contributing to elucidate which genes are most implicated in TNBC development with respect to the remaining breast cancer subtypes. A breast cancer patients sample comprised of 100 triple negative breast cancer patients and 100 other breast cancer subtypes patients were analyzed by Next-Generation Sequencing using an On-Demand panel which included 35 predisposition cancer genes associated with inherited cancer susceptibility. Triple negative breast cancer patients obtained a higher percentage of germline variant carriers. ATM, PALB2, BRIP1 and TP53 were the most non-BRCA mutated genes. Moreover, triple negative breast cancer patients without family history related which proved to be carriers were diagnosed at significant earlier age. As conclusion, our study reinforces the usefulness of multigene panel testing in breast cancer cases but specifically in those with triple negative subtype regardless family history.
