| Gene Variant Descriptions | MLH1 Q701K lies within the C-terminal dimerization domain of the Mlh1 protein (PMID: 22753075). The functional effect of Q701K is conflicting as it retains interaction with Pms2 (PMID: 18094436, PMID: 30504929) and nuclear localization in culture (PMID: 30504929), but results in reduced Mlh1 expression and altered subcellular localization in patient samples (PMID: 22136435), decreased interaction with Pms2 in a yeast assay (PMID: 18094436), and decreased mismatch repair activity in an in vitro assay (PMID: 30504929), and therefore, its effect on Mlh1 protein function is unknown. |
