Invitae RCV000793206 SCV000932547 uncertain significance Hereditary nonpolyposis colon cancer 2018-08-01 criteria provided, single submitter clinical testing This sequence change affects codon 819 of the PMS2 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the PMS2 protein. The frequency data for this variant in the population databases (rs786203315, ExAC) is considered unreliable due to the presence of homologous sequence, such as pseudogenes or paralogs, in the genome. This variant has not been reported in the literature in individuals with PMS2-related disease. ClinVar contains an entry for this variant (Variation ID: 186908). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. 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.
