Invitae | RCV000824668 | SCV000965575 | uncertain significance | Hereditary nonpolyposis colorectal neoplasms | 2019-12-10 | criteria provided, single submitter | clinical testing | This variant results in a copy number gain of the genomic region encompassing exons 1-12 of the PMS2 gene. The 5' end of this event is unknown as it extends beyond the assayed region for this gene and therefore may encompass additional genes. The 3' boundary is likely confined to intron 12 of the PMS2 gene. As the precise location of this event is unknown, it may be in tandem or it may be located elsewhere in the genome. A duplication encompassing exons 1-12 of the PMS2 gene has been reported in an individual affected with colorectal cancer. High levels of microsatellite instability and loss of PMS2 protein were found in the tumor (PMID: 22120844). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |
