GeneDx RCV000212592 SCV000211243 benign not specified 2014-09-09 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.

Mutation Taster predicts a damaging outcome for this variant, and 2/5 Alamut algorithms predict no significant change to normal splicing and no changes to ESE binding sites. The variant of interest has not been evaluated for functional impact by in vivo/vitro studies. This variant is found in 31/121148 control chromosomes at a frequency of 0.0002559, which does not significantly exceed maximal expected frequency of a pathogenic allele (0.0005683). However, the allele frequency in Africans (29/10308; 0.002813) is 5-fold greater than the maximal expected allele frequency for a pathogenic MSH2 variant, suggesting that this is a benign polymorphism found in Africans. In addition, clinical laboratories classified this variant as likely benign/benign. Taken together, this variant was classified as benign.

Illumina Clinical Services Laboratory,Illumina RCV001139365 SCV001299508 uncertain significance Lynch syndrome I 2018-01-12 criteria provided, single submitter clinical testing This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.
