GENE  MUTATION AND TUMOR

Lynch syndrome (LS) is a high penetrance, autosomal dominant susceptibility syndrome.The pathogenesis of LS is single allele germline mutation of mismatch repair genes (especially MLH1, MSH2, MSH6 or PMS2), or epigenetic silencing of MSH2 caused by germline deletion in adjacent EPCAM gene. LS can cause colorectal cancer and tumors in other organs (including endometrium, ovary, stomach, small intestine, liver and gallbladder, upper urethra, brain and skin). The cancer risk of LS carrier is higher than that of normal people.


NCCN guidelines recommend that all patients with newly diagnosed colorectal cancer should be screened by immunohistochemistry or microsatellite instability detection of four MMR proteins (MSH2, MSH6, PMS2, MLH1) in tumor tissue.For dMMR patients identified by immunohistochemistry, it is suggested to further detect germline mutations of protein expression deletion genes.For patients with microsatellite instability determined by MSI method, germline mutation detection of MSH2, MSH6, PMS2, MLH1 and EPCAM genes is recommended.
