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]

Hereditary cancer-predisposing syndrome Benign:2
Feb 01, 2019
Ambry Genetics
Significance:Likely benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This alteration is classified as likely 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. -

Variant summary: MSH2 c.287G>A (p.Arg96His) results in a non-conservative amino acid change located in the N-terminal domain (IPR007695) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 2e-05 in 251288 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.287G>A has been reported in the literature together with an MSH2 frameshift variant in a family affected with Lynch Syndrome, authors noted that the variant of interest did not segregate with the disease (Wijnen_1995). In addition, a co-occurrence with a (likely) pathogenic variant has also been reported (RAD51C c.1026+5_1026+7delGTA; in an LCA internal sample), providing supporting evidence for a benign role. Publications also reported experimental evidence evaluating an impact on protein function, and demonstrated no effect on MMR activity for this variant (Martinez_2010, Houlleberghs_2016). Six submitters, including an expert panel (InSiGHT), have provided clinical-significance assessments for this variant in ClinVar without evidence for independent evaluation, and all of them classified the variant as likely benign. Based on the evidence outlined above, the variant was classified as likely benign. -
