| Gene Variant Descriptions | MLH1 L676P lies within the C-terminal dimerization domain of the Mlh1 protein (PMID: 22753075). L676P retains subcellular localization and interaction with Pms2 comparable to wild-type (PMID: 26437257) but demonstrates decreased protein expression compared to wild-type in culture and decreased mismatch repair activity in an in vitro assay (PMID: 29520894), and therefore, is predicted to lead to a loss of Mlh1 protein function. |
