Invitae | RCV000168283 | SCV000218956 | likely pathogenic | Lynch syndrome | 2015-05-22 | criteria provided, single submitter | clinical testing | This sequence change is a gross duplication of the genomic region encompassing exon 7 of the MSH2 gene. While the exact position of the duplicated exon cannot be determined from this data, the most likely explanation is that it occurs in tandem and results in an absent or disrupted protein product. A similar duplication of exon 7 in the MSH2 gene has been reported previously in a patient affected with colorectal cancer (PMID: 15713769). If this exon 7 duplication is in tandem, it would likely result in a frameshift leading to a premature translational stop signal and an absent or disrupted MSH2 protein. Given the likelihood that this is an intragenic duplication, it has been classified as Likely Pathogenic. |
