Methods: A multigene next-generation sequencing panel was used to screen 75 index cases with colorectal polyps and a personal/family history of cancer for key hereditary polyposis-associated genes (APC, BMPR1A, MUTYH, PTEN, SMAD4, and STK11) in order to identify germline genetic variants. The gene discussed is STK11; the disease is polyp of large intestine.
