| Gene Variant Descriptions | MLH1 E578G lies within the EXO1-interacting region and C-terminal dimerization domain of the Mlh1 protein (PMID: 22753075). E578G results in stable Pms2 and Mlh1 expression and mismatch repair activity comparable to wild-type in culture in one study (PMID: 36054288), but in others demonstrates a loss of mismatch repair activity in in vitro assays (PMID: 20020535, PMID: 17510385) and loss of interaction with Pms2 (PMID: 11292842), and therefore, its effect on Mlh1 protein function is unknown. |
