This study has been mainly focused on the two most prevalent HC syndromes: hereditary breast and ovarian cancer and hereditary colorectal cancer, although data on other less prevalent cancer syndromes are also presented. Specific aims 1. To elucidate the role of new candidate cancer-predisposing genes and to devise new genotype-phenotype correlations. 2. To improve the classification of VUS. 3. To increase the mutation detection rate of the studied genes, following two different approaches: 3.1. Implementation of somatic testing in unsolved hereditary cancer patients with two goals: to assess the prevalence of mosaicism and to evaluate the frequency of double somatic hits among Lynch-like syndrome patients. 3.2. Implementation of new testing strategies complementary to DNA-based sequencing to address mutational discovery in previously unexplored regions.287 p.application/pdfeng(c) Rofes Terrón, Paula, 2022Malalties hereditàriesCàncerDiagnòstic molecularCiències de la salutGenetic diseasesCancerMolecular diagnosisMedical sciencesinfo:eu-repo/semantics/doctoralThesisinfo:eu-repo/semantics/openAccesshttp://hdl.handle.net/10803/674597
