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]

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -

The PMS2 p.Thr511Met variant was identified in the literature however the frequency of this variant in an affected population was not provided. The variant was also identified in dbSNP (ID: rs74902811) as With other allele, ClinVar (classified as benign by InSight, Ambry Genetics, Prevention Genetics, Color Genimics, Invitae; classified as likely benign by Vantary genetics, Illumina), Clinvitae (classified with conflicting interpretations of pathogenicity), MutDB , Insight Colon Cancer Gene Variant Database (2X class1), Insight Hereditary Tumors Database (2X class1), databases. The variant was not identified in Cosmic, Zhejiang Colon Cancer Database, Mismatch Repair Genes Variant Database, databases. The variant was identified in control databases in 2670(84 homozygous) of 277088 chromosomes at a frequency of 0.009636 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Consortium Feb 27, 2017). The variant was identified in the following populations at a frequency greater than 1%: African in 1930 of 24008 chromosomes (freq: 0.08), EastAsian in 549 of 18862 chromosomes (freq: 0.029). In cell free assay by Drost (2013) the variant not classified as repair deficient and might be pathogenic with reduced penetrance. Tthe variant classified as benign by ACMG-AMP classification for consensus variants (Amendola 2016). The p.Thr511 residue is not conserved in mammals and four out of five computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein; however, this information is not predictive enough to rule out pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) do not predict a difference in splicing. In summary, based on the above information this variant meets our laboratory's criteria to be classified as benign. -
