GeneDx RCV000202106 SCV000149315 likely benign not specified 2017-11-01 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.

Integrated Genetics/Laboratory Corporation of America RCV000202106 SCV000919760 likely benign not specified 2018-09-24 criteria provided, single submitter clinical testing Variant summary: MSH6 c.3217C>T (p.Pro1073Ser) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00041 in 277092 control chromosomes, predominantly at a frequency of 0.0077 within the Ashkenazi Jewish subpopulation in the gnomAD database. The observed variant frequency within Ashkenazi Jewish control individuals in the gnomAD database is approximately 54.2 fold of the estimated maximal expected allele frequency for a pathogenic variant in MSH6 causing Lynch Syndrome phenotype (0.00014), strongly suggesting that the variant is a benign polymorphism found primarily in populations of Ashkenazi Jewish origin. c.3217C>T has been reported in the literature in individuals affected with Lynch Syndrome. These report(s) do not provide unequivocal conclusions about association of the variant with Lynch Syndrome. Seven clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. Multiple laboratories reported the variant with conflicting assessments. Based on the evidence outlined above, the variant was classified as likely benign.
