Invitae RCV001032161 SCV001195468 likely pathogenic Hereditary nonpolyposis colorectal neoplasms 2019-09-01 criteria provided, single submitter clinical testing This sequence change is a gross duplication of the genomic region encompassing exons 1-6 of the MSH2 gene. If EPCAM has been tested and no copy number events are reported for it, then the 5' boundary of this event lies between the EPCAM and MSH2 genes. If EPCAM has not been tested, the 5' end of this event is unknown as it extends beyond the assayed region of this test. The 3' boundary is likely confined to intron 6 of the MSH2 gene. The exact location of this variant in the genome is unknown. Gains of exons 1-6 have been observed in individuals affected with Lynch syndrome (Invitae). Several of these individuals were affected with colorectal cancer, endometrial cancer and/or sebaceous adenomas that showed loss of MSH2/MSH6 expression. ClinVar contains an entry for this variant (Variation ID: 254049). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
