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]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

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 rule this variant out of causing disease. Therefore, this variant is classified as benign. -

PMS2, Exon14, c.2324A>G, p. Asn775Ser, Benign, ACMG 5 The c.2324A>G variant was identified in 32 of 1428 proband chromosomes (frequency: 0.022) from individuals or families with HNPCC or Lynch syndrome (20698049_sheng_2010, 14756672_Thompson_2004, Clendenning_2006_16619239); however, control chromosomes were not evaluated in these studies, thus the prevalence of this variant in the general population could not be determined. The variant was also identified in dbSNP (ID: rs17420802 ) â€šÃ„ÃºWith benign alleleâ€šÃ„Ã¹, HGMD, COSMIC, â€šÃ„ÃºMismatch Repair Genes Variant Databaseâ€šÃ„Ã¹, â€šÃ„ÃºInSiGHT Colon Cancer Databaseâ€šÃ„Ã¹, and the ClinVar database by 7 submitters as benign. The p.Asn775 residue is conserved across mammals and lower organisms, and four out of five computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) suggest that the p.Asn775Ser variant may impact the protein. However, this information is not predictive enough to assume pathogenicity. Computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein. The c.2324A>G variant occurs outside of the splicing consensus sequence and in silico or computational prediction software (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) does not predict a difference in splicing in 5 of 5 different programs. (However, this information is not predictive enough to rule out pathogenicity.) In summary, based on the above information, this variant meets our laboratory's criteria to be classified as benign. -
