Genes affected

PMS2 (HGNC:9122): (PMS1 homolog 2, mismatch repair system component) The protein encoded by this gene is a key component of the mismatch repair system that functions to correct DNA mismatches and small insertions and deletions that can occur during DNA replication and homologous recombination. This protein forms heterodimers with the gene product of the mutL homolog 1 (MLH1) gene to form the MutL-alpha heterodimer. The MutL-alpha heterodimer possesses an endonucleolytic activity that is activated following recognition of mismatches and insertion/deletion loops by the MutS-alpha and MutS-beta heterodimers, and is necessary for removal of the mismatched DNA. There is a DQHA(X)2E(X)4E motif found at the C-terminus of the protein encoded by this gene that forms part of the active site of the nuclease. Mutations in this gene have been associated with hereditary nonpolyposis colorectal cancer (HNPCC; also known as Lynch syndrome) and Turcot syndrome. [provided by RefSeq, Apr 2016]

Hereditary cancer-predisposing syndrome

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Mar 13, 2023	This variant is located in the 3' untranslated region of the PMS2 gene. To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has been identified in 5/219538 chromosomes in the general population by the Genome Aggregation Database (gnomAD). However, this observed allele frequency is not considered reliable since the gnomAD dataset does not disambiguate possible interference from homologous sequences in the PMS2CL pseudogene. The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -
Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Mar 06, 2017	The c.*3G>A variant is located in the 3' untranslated region (3’ UTR) of the PMS2 gene. This variant results from a G to A substitution 3 nucleotides downstream of the last translated codon. Based on nucleotide sequence alignment, this position is poorly conserved in available vertebrate species. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

Uncertain significance, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Apr 18, 2024	Variant summary: PMS2 c.3G>A is located in the untranslated mRNA region downstream of the termination codon. Consensus agreement among computation tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 1.5e-05 in 199080 control chromosomes in the gnomAD database, including 1 homozygotes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.3G>A in individuals affected with Hereditary Nonpolyposis Colorectal Cancer and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 185828). Based on the evidence outlined above, the variant was classified as uncertain significance. -

Uncertain significance, criteria provided, single submitter	clinical testing	Quest Diagnostics Nichols Institute San Juan Capistrano	May 01, 2023	This variant has not been reported in the published literature. The frequency of this variant in the general population, 0.000058 (1/17120 chromosomes, http://gnomad.broadinstitute.org), is uninformative in assessment of its pathogenicity. Based on the available information, we are unable to determine the clinical significance of this variant. -

Apr 19, 2024

The PMS2 c.*3G>A variant is located in the 3' untranslated region. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0058% of alleles in individuals of African descent in gnomAD and has conflicting interpretations regarding its pathogenicity in ClinVar, ranging from benign to uncertain (https://www.ncbi.nlm.nih.gov/clinvar/variation/185828/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
