Variant summary: The MSH2 c.885C>G (p.Asp295Glu) variant located in the DNA mismatch repair protein MutS, connector domain (via InterPro) involves the alteration of a non-conserved nucleotide and 3/4 in silico tools (SNPsandGO not captured due to low reliability index) predict a benign outcome. However, these predictions have yet to be functionally assessed. This variant was found in 7/121246 control chromosomes at a frequency of 0.0000577, which does not exceed the estimated maximal expected allele frequency of a pathogenic MSH2 variant (0.0005683). A publication, Pal_2012, cites the variant in an affected individual with limited information (ie, lack of co-occurrence and cosegregation data). In addition, multiple clinical diagnostic laboratories report the variant with conflicting classifications, "likely benign" or "uncertain significance." Therefore, until additional information becomes available (ie, clinical and functional studies), the variant of interest has been classified as a "Variant of Uncertain Significance (VUS)." (less)

This missense variant replaces aspartic acid with glutamic acid at codon 295 of the MSH2 protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). Splice site prediction tools suggest that this variant may not impact RNA splicing. This variant does not impact MSH2 function in a 6-thioguanine sensitivity assay in haploid human cells (internally defined LOF score threshold <= -1.32, PMID: 33357406). This variant has been reported in an individual affected with ovarian cancer (PMID: 23047549) and an individual affected with kidney carcinoma (PMID: 29684080). This variant has also been identified in 12/251032 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. (less)

This date represents the last time this VCV record was updated. The update may be due to an update to one of the included submitted records (SCVs), or due to an update that ClinVar made to the variant such as adding HGVS expressions or a rs number.
