Invitae RCV001089791 SCV001245285 pathogenic Hereditary nonpolyposis colorectal neoplasms 2019-10-29 criteria provided, single submitter clinical testing This sequence change inserts a large fragment of DNA, likely a transposable element, in exon 5 of the MSH2 gene (c.882_883insSVA), causing a frameshift at codon 295 (p.Asp295fs). The exact size and sequence of the insertion cannot be determined by the current assay. However, the insertion is expected to result in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with MSH2-related conditions. Retrotransposon insertions including LINE1 (L1), Alu, and SVA (SINE-VNTR-Alu) have been reported to be disease-causing through disruption of either a coding region or splice site (PMID: 19763152, 20307669, 22406018) and loss-of-function variants in MSH2 are known to be pathogenic (PMID: 15849733, 24362816). For these reasons, this variant has been classified as Pathogenic.
