Recently, two large case/control studies have revealed that 8 genes are significantly associated with breast cancer: BRCA1, BRCA2, PALB2, CHEK2, ATM, BARD1, RAD51C and RAD51D. Screening of these genes using high-throughput sequencing has allowed the detection of thousands of variants, many of them classified as variants of unknown significance (VUS). Interestingly, splicing dysregulation is a prevalent etiopathogenic mechanism in breast cancer susceptibility genes. In this context, functional splicing assays of potentially spliceogenic variants reported in breast cancer susceptibility genes will allow the reclassification of a large fraction of VUS. The aim of this PhD thesis is to functionally and clinically classify splice site variants identified in the breast cancer predisposition genes CHEK2 and RAD51C, as well as to characterize the regulatory mechanisms involved in the inclusion of exons subject to alternative splicing, such as exons 8 and 10 of CHEK2, and special exons, such as BARD1 exon 4 (macroexon) and BRIP1 exon 1 (GC donor).
