| Gene Variant Descriptions | MLH1 A42V lies within the ATPase domain of the Mlh1 protein (PMID: 22753075). The functional effect of A42V is conflicting as it results in decreased mismatch repair (MMR) activity in a yeast assay (PMID: 15475387), reduced Pms2 and Mlh1 expression and altered splicing, but leads to normal MMR activity in culture (PMID: 36054288). |
