Molecular analysis of BRCA1 and BRCA2 genes in La Rioja (Spain): five new variants.

Background: To study BRCA1/2 gene variants in La Rioja in the northcentral area of Spain.

Methods: We performed a molecular analysis of BRCA1 and BRCA2 in 642 individuals from 427 different families from June 2008 to December 2019.

Results: We identified 71 families with pathogenic variants in these genes, 32 families with BRCA1 variants and 39 families with BRCA2 variants.
