Approximately 5¿10% of cases have a hereditary origin, associated with germline loss-of-function variants in eight major susceptibility genes: ATM, BARD1, BRCA1, BRCA2, CHEK2, PALB2, RAD51C, and RAD51D. The use of high-throughput sequencing techniques to identify deleterious variants in these genes has markedly increased the detection of variants of uncertain clinical significance (VUS). Many of these variants can disrupt the splicing process, a predominant etiopathogenic mechanism in hereditary cancer. In this context, functional splicing assays are essential to assess the pathogenic potential of such variants, supporting the reclassification of VUS. The objectives of this thesis are: (1) functional and clinical interpretation of splice-site variants identified in the ATM gene; (2) regulation of alternatively spliced and atypical exons in ATM and TP53, and the impact of genetic variation; and (3) investigation of non-canonical splicing.
