RCV000524364 | SCV000260744 | pathogenic | Hereditary nonpolyposis colorectal neoplasms | 2023-11-24 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Arg621*) 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 not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with Lynch syndrome and colorectal cancer (PMID: 8566964, 12624141, 17569143, 18772310, 20007843, 21598002, 21642682, 24415873). ClinVar contains an entry for this variant (Variation ID: 90804). For these reasons, this variant has been classified as Pathogenic. |

Ambry Genetics | RCV000491286 | SCV000580383 | pathogenic | Hereditary cancer-predisposing syndrome | 2021-10-21 | criteria provided, single submitter | clinical testing | The p.R621* pathogenic mutation (also known as c.1861C>T), located in coding exon 12 of the MSH2 gene, results from a C to T substitution at nucleotide position 1861. This changes the amino acid from an arginine to a stop codon within coding exon 12. This mutation has been reported in multiple HNPCC/Lynch syndrome families; several who meet Amsterdam criteria and/or have tumors that demonstrated loss of MSH2 and MSH6 by IHC (Maliaka YK et al. Hum. Genet. 1996 Feb;97(2):251-5; Weber TK et al. Cancer Res. 1997 Sep;57(17):3798-803; Niessen RC et al. Gut 2006 Dec;55(12):1781-8; Overbeek LIH et al. Br. J.

Hered Cancer Clin Pract, 2019 Oct;17:29; Wischhusen JW et al. Cancer Epidemiol Biomarkers Prev, 2020 01;29:193-199; Shao D et al. Cancer Sci, 2020 Feb;111:647-657; Yanus GA et al. Eur J Med Genet, 2020 Mar;63:103753; Akcay IM et al. Int J Cancer, 2021 01;148:285-295). 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. |

RCV000491286 | SCV000684988 | pathogenic | Hereditary cancer-predisposing syndrome | 2022-05-06 | criteria provided, single submitter | clinical testing | This variant changes 1 nucleotide in exon 12 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 affected with Lynch syndrome or suspected of having Lynch syndrome (PMID: 8566964, 12624141, 17569143, 18772310, 20007843, 21598002, 21642682, 27629256), or colorectal cancer (PMID: 24415873, 26552419, 29967336). This variant has not been identified 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. |

RCV001328039 | SCV000696226 | pathogenic | Hereditary nonpolyposis colon cancer | 2021-03-04 | criteria provided, single submitter | clinical testing | Variant summary: MSH2 c.1861C>T (p.Arg621X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have been classified as pathogenic by our laboratory. The variant was absent in 251474 control chromosomes. c.1861C>T has been reported in the literature in multiple individuals affected with MSH2-associated cancers (Maliaka_1996, Papp_2007, Bonadona_2011, Vierkoetter_2014, Kang_2015, Dominguez-Valentin_2016). These data indicate that the variant is very likely to be associated with disease. Seven clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. |
