Invitae | RCV000477665 | SCV000253797 | pathogenic | Lynch syndrome | 2016-10-03 | criteria provided, single submitter | clinical testing | This sequence change is a gross deletion of the genomic region encompassing exon 8 of the MSH2 gene. This deletion disrupts the reading frame of the gene and is expected to result in an absent or disrupted protein product. Loss-of-function variants including gross deletions in MSH2 are known to be pathogenic. Deletions of exon 8 have been reported in several individuals and families affected with Lynch syndrome (PMID: 22781090, 10190329, 25117500, 16143124, 15942939, 15713769, 21388660). Protein expression studies in colon tumors of a Lynch syndrome patient carrying this deletion were shown to have a lack of expression of the MSH2 protein (PMID: 15713769). For these reasons, this variant has been classified as Pathogenic. |
