GeneDx RCV000202010 SCV000149434 likely benign not specified 2017-10-27 criteria provided, single submitter clinical testing This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.

This variant was found in 9/123686 control chromosomes at a frequency of 0.0000728, which does not exceed the estimated maximal expected allele frequency of a pathogenic MSH2 variant (0.0005683). This variant has been reported in a proband from LS family with lack of co-segregation of this variant with disease. This patient also carried a pathogenic variant in MLH1, which could explain the patients phenotype. The variant of interest has also been reported in a case-control study with comparable allele frequency detected in the control and case cohorts. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as benign/likely benign and two clinical labs classified this variant as VUS, all without evidence to independently evaluate. Taken together, the variant was classified as likely benign until additional information becomes available.
