| Gene Variant Descriptions | MLH1 S247P lies within the ATPase domain of the Mlh1 protein (PMID: 22753075). S247P results in stable Mlh1 and Pms2 expression but confers a loss of function to the Mlh1 protein as demonstrated by reduced mismatch repair activity in culture (PMID: 36054288) and in an in vitro assay (PMID: 16083711), altered subcellular localization, and reduced protein expression compared to wild-type Mlh1 in culture (PMID: 21120944). |
