In this study, we aim to gain insight in the germline mutation spectrum of , , , , , and in breast and ovarian cancer families from Spain. We have selected 180 index cases in whom a germline mutation in BRCA1 and BRCA2 was previously ruled out. The importance of disease-causing variants in these genes lies in the fact that they may have possible therapeutic implications according to clinical guidelines.

Our standard diagnostic approach focuses on sequencing a few classic high-risk genes, a method that frequently renders uninformative genetic results. This study aims to examine the improved yield offered by an On-Demand panel.

Germline PALB2 inactivating mutations were associated with an increased risk of HBOC due to its role in DNA repair through cooperation with BRCA proteins. The prevalence and penetrance of PALB2 mutations in Spanish HBOC patients remains unexplained.
View Article and Find Full Text PDFBRIP1 is a component of the Fanconi Anemia/BRCA pathway responsible for DNA reparation via helicase activity. Some heterozygous variants in BRIP1 could contribute to Hereditary Breast Cancer through a defective DNA repair. The clinical utility of BRIP1 mutations in a familial cancer context is compromised by the conflicting interpretation of "variants of uncertain significance" (VUS).
