Lynch syndrome has historically been known as Hereditary Non Polyposis Colorectal Cancer (HNPCC). The high MSI in cases of colorectal cancer reflects a difference in the biologic features of the tumor, possibly with a unique susceptibility to immunotherapy. Lynch Syndrome Definition and Types LS, formerly known as hereditary nonpolyposis colorectal cancer or HNPCC was firstly described by Warthin in 1913 and it is an autosomal dominant disease caused by germline mutation in MMR genes MLH1, MSH2, MSH6 and PMS2, or by germline mutation in EPCAM which causes epigenetic silencing of MSH2 6, 7.
