Invitae | RCV000533871 | SCV000624595 | likely pathogenic | Hereditary nonpolyposis colorectal neoplasms | 2019-02-27 | criteria provided, single submitter | clinical testing | This variant results in a copy number gain of the genomic region encompassing exons 11-12 of the PMS2 gene. While the exact position of this variant cannot be determined from this data, sub-genic copy number gains are generally in tandem (PMID: 25640679) and may result in an absent or disrupted protein product. Similar duplications of exons 11-12 have been reported in individuals with suspected constitutional mismatch repair deficiency syndrome and Lynch syndrome (PMID: 26320870, 25512458). Loss-of-function variants in PMS2 are known to be pathogenic (PMID: 21376568, 24362816). 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. |
