Invitae RCV000469067 SCV000559200 likely benign Hereditary nonpolyposis colon cancer 2017-11-28 criteria provided, single submitter clinical testing
GeneDx RCV000613916 SCV000728999 likely benign not specified 2017-02-10 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 RCV000613916 SCV000917705 uncertain significance not specified 2018-06-15 criteria provided, single submitter clinical testing Variant summary: MSH2 c.2634+7C>G alters a non-conserved nucleotide located close to a canonical splice site and therefore could affect mRNA splicing, leading to a significantly altered protein sequence. 5/5 computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 6.5e-05 in 30980 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.2634+7C>G in individuals affected with Lynch Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. Two clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation, and both laboratories classified the variant as likely benign. Based on the evidence outlined above, the variant was classified as uncertain significance.
