Invitae RCV000477663 SCV000299118 pathogenic Lynch syndrome 2017-01-15 criteria provided, single submitter clinical testing This variant is a gross deletion of the genomic region encompassing exons 8-15 of the MSH2 gene. This deletion is expected to create a premature translational stop signal in the last exon of the MSH2 mRNA. While this is not anticipated to result in nonsense mediated decay, it is expected to result in the loss of nearly half of the MSH2 coding sequence. Gross deletions of exons 8-15 have been reported in the literature in individuals affected with Lynch syndrome (PMID: 8062247, 25980754). In addition, several pathogenic missense variants have been reported in exons 8-15 of MSH2 (PMID: 21419771, 23690608, 18951462), which further indicates this deletion likely disrupts protein function. For these reasons, this variant has been classified as Pathogenic.
