Gene Variant Descriptions | MLH1 A492T lies within the EXO1-interacting region and C-terminal dimerization domain of the MLH1 protein (PMID: 22753075). A492T results in repression activity similar to wild-type Mlh1 in a yeast reporter assay and interaction with Pms2 similar to wild-type Mlh1 in a yeast two-hybrid assay, but results in decreased Exo1 interaction in a yeast two-hybrid assay, decreased Pms2 binding in an in vitro assay (PMID: 12810663), and decreased MMR activity in an in vitro assay (PMID: 17510385), and therefore, is predicted to lead to a loss of Mlh1 protein function. |
