GeneDx RCV000436098 SCV000513686 benign not specified 2015-03-31 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.

One in-silico tool predicts damaging outcome for this variant, and 2/5 Alamut algorithms predict a change in a cryptic splice acceptor site. This variant was found in 7/120720 control chromosomes at a frequency of 0.000058, which does not significantly exceed maximal expected frequency of a pathogenic MSH6 allele (0.0001421). However, the variant was predominantly found in East Asians, at an allele frequency of 0.0006935, which is significantly greater than the maximal expected allele frequency, suggesting this may be a benign polymorphism in East Asians. In addition, several clinical laboratories classified this variant as likely benign without evidence to independently evaluate. The variant of interest has not, to our knowledge, been reported in affected individuals via publications, nor evaluated for functional impact by in vivo/vitro studies. Taken together, this variant was classified as likely benign until additional information is available.
