| Gene Variant Descriptions | MLH1 K618del results in the deletion of an amino acid in the EXO1-interacting region and C-terminal dimerization domain of the Mlh1 protein at amino acid 618 (PMID: 22753075). K618del (reported as K616del) results in altered subcellular localization, reduced protein expression compared to wild-type Mlh1 in culture (PMID: 21120944), reduced interaction with Pms2 and Exo1 in a yeast two-hybrid assay (PMID: 12810663), and loss of mismatch repair activity in an in vitro assay (PMID: 29520894). |
