Invitae RCV000534549 SCV000625146 uncertain significance Hereditary nonpolyposis colon cancer 2017-06-09 criteria provided, single submitter clinical testing This sequence change replaces serine with glycine at codon 106 of the MLH1 protein (p.Ser106Gly). The serine residue is highly conserved and there is a small physicochemical difference between serine and glycine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with an MLH1-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. In summary, this variant has uncertain impact on MLH1 function. The available evidence is currently insufficient to determine its role in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
