In this context, we built an NGS custom pan-cancer panel containing 16 high and moderate penetrance genes previously associated with hereditary cancer syndromes (APC, BRCA1, BRCA2, CDH1, CDKN2A, CHEK2, MSH2, MSH6, MUTYH, PTEN, RB1, RET, TP53, VHL, XPA and XPC) [10, 11]. The gene discussed is MUTYH; the disease is cancer.
