WebGermline MLH1 promoter hypermethylation may confer an HNPCC (Lynch) syndrome phenotype even in the absence of primary sequence alternations in the MLH1 gene. Germline MLH1 promoter methylation can be documented by detecting methylation in non-neoplastic tissue (peripheral blood). WebDefective MMR in sporadic colon cancer is most often due to an abnormality in MLH1, and the most common cause of gene inactivation is promoter hypermethylation (epigenetic silencing). A specific alteration in the BRAF gene (V600E) has been shown to be present in approximately 70% of tumors with hypermethylation of the MLH1 promoter.
