| Protein Effect | loss of function - predicted |
| Gene Variant Descriptions | MLH1 C77Y lies within the ATPase domain of the Mlh1 protein (PMID: 22753075). C77Y results in decreased Mlh1 stability (PMID: 31697235), decreased mismatch repair (MMR) activity in an in vitro assay (PMID: 17510385), and decreased interaction with Pms2 and Exo1 in a yeast two-hybrid assay (PMID: 12810663), and therefore, is predicted to lead to a loss of Mlh1 protein function. |
