WebOver time, cancer will nearly always develop in one or more of these polyps. Lynch syndrome (hereditary non-polyposis colon cancer, or HNPCC) is caused by changes in genes that normally help a cell repair damaged DNA. A mutation in one of the DNA repair genes like MLH1, MSH2, MSH6, PMS2, and EPCAM, can allow DNA errors to go unfixed.
