In particular, we adopted the Hereditary Cancer Solution CE-IVD kit (SOPHiA Genetics, Saint-Sulpice, Switzerland), a NGS capture-based target enrichment of 26 cancer related genes (ATM, APC, BARD1, BRCA1, BRCA2, BRIP1, CDH1, CHEK2, EPCAM, FAM175A, MLH1, MRE11A, MSH2, MSH6, MUTYH, NBN, PALB2, PIK3CA, PMS2, PMS2C, PTEN, RAD50, RAD51C, RAD51D, STK11, TP53, XRCC2). This evidence concerns the gene PIK3CA and cancer.
