Genes affected
MSH2 (HGNC:7325): (mutS homolog 2) This locus is frequently mutated in hereditary nonpolyposis colon cancer (HNPCC). When cloned, it was discovered to be a human homolog of the E. coli mismatch repair gene mutS, consistent with the characteristic alterations in microsatellite sequences (RER+ phenotype) found in HNPCC. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2012]

Lynch syndrome 1 Pathogenic:4
Pathogenic, criteria provided, single submitter | clinical testing | KCCC/NGS Laboratory, Kuwait Cancer Control Center | Jul 31, 2024 | This sequence change creates a premature translational stop signal (p.Arg680*) in the MSH2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in MSH2 are known to be pathogenic (PMID: 15849733, 24362816). This variant is present in population databases (rs63749932, gnomAD 0.0009%). This premature translational stop signal has been observed in individual(s) with Lynch syndrome (PMID: 20215533, 12547705, 15713769, 25648859, 20587412, 24344984, 32549215, 31830689, 29922827, 28888541, 34761457, 31615790, 9311737, 21598002, 23047549, 12414824, 16807412, 18809606, 9718327, 11524701, 11854906, 11208710, 27318266, 18270343, 27013479, 16616355, 15345113, 15849733, 20233461, 19723918, 17312306, 15926618, 12658575, 12112654, 18566915, 27601186, 25980754, 25430799, 26681312, 28176205, 28944238, 29489754, 28874130, 30521064, 30322717, 31939059, 29625052, 31447099, 34178123, 30217226, 32719484, 30787465, 30998989) . ClinVar contains an entry for this variant (Variation ID: 36572).

Pathogenic, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Mar 20, 2017 | The p.Arg680X variant in MSH2 has been reported in at least 5 individuals with L ynch syndrome-associated cancers (Hendriks 2003, Walsh 2010, Sjursen 2010, Pal 2 012, Dominguez-Valentin 2016). In addition, tumors sampled from 3 individuals sh owed microsatellite instability and lacked MSH2 and MSH6 expression. This varian t has also been identified in 1/66702 of European chromosomes by the Exome Aggre gation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs63749932). This nonsense variant leads to a premature termination codon at position 680, which is predicted to lead to a truncated or absent protein. Heterozygous loss of func tion of the MSH2 gene is an established disease mechanism in individuals with Ly nch Syndrome. Furthermore, the p.Arg680X variant has been classified as pathogen ic on by the ClinGen-approved InSiGHT expert panel (ClinVar SCV000107394.2). In summary, this variant meets criteria to be classified as pathogenic for Lynch S yndrome in an autosomal dominant manner based upon the predicted impact to the p rotein. - |

Hereditary cancer-predisposing syndrome Pathogenic:2
Pathogenic, criteria provided, single submitter | clinical testing | Color Diagnostics, LLC DBA Color Health | Oct 11, 2023 | This variant changes 1 nucleotide in exon 13 of the MSH2 gene, creating a premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. To our knowledge, functional studies have not been reported for this variant. This variant has been reported in individuals and families affected with Lynch syndrome and/or Lynch syndrome-associated disease (PMID: 12547705, 20587412, 21879275, 23047549, 24344984, 25430799, 27013479, 27601186), as well as in individuals affected with breast cancer or prostate cancer whose tumors displayed abnormal MSH2/MSH6 protein via immunohistochemistry (PMID: 19723918, 20215533). This variant has been identified in 1/251446 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Loss of MSH2 function is a known mechanism of disease (clinicalgenome.org). Based on the available evidence, this variant is classified as Pathogenic. - |
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Mar 09, 2022 | The p.R680* pathogenic mutation (also known as c.2038C>T), located in coding exon 13 of the MSH2 gene, results from a C to T substitution at nucleotide position 2038. This changes the amino acid from an arginine to a stop codon within coding exon 13. This mutation has been identified in multiple individuals/families with HNPCC/Lynch syndrome (Jenkins MA et al. Clin. Gastroenterol. Hepatol. 2006 Apr;4:489-98; Levi Z et al. Am. J. Transplant. 2007 Feb;7:476-9; Brieger A et al. Fam. Cancer. 2011 Sep;10:591-5; Pal T et al. Br. J.

Genomic Med. 2017 Jul;5:553-569; Rossi BM et al. BMC Cancer. 2017 Sep;17:623). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. - |

Lynch syndrome 4 Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Clinical Genomics Laboratory, Washington University in St. Louis | Jan 03, 2024 | The MSH2 c.2038C>T (p.Arg680Ter) variant has been reported in many individuals affected with Lynch syndrome (Álvarez K et al., PMID: 32549215; Goldberg Y et al., PMID: 25430799; Jiang W et al., PMID: 30521064; Lagerstedt-Robinson K et al., PMID: 27601186; Zhang J et al., PMID: 35939113). This variant has been reported in the ClinVar database as a germline pathogenic variant by 16 submitters, including an expert panel. This variant is only observed on 1/251,446 alleles in the general population (gnomAD v.2.1.1), indicating it is not a common variant. This variant causes a premature termination codon, which is predicted to lead to nonsense mediated decay. Based on available information and the ACMG/AMP guidelines for variant interpretation (Richards S et al., PMID: 25741868), this variant is classified as pathogenic. - |
