Color Diagnostics, LLC DBA Color Health RCV001191976 SCV001359919 uncertain significance Hereditary cancer-predisposing syndrome 2023-12-04 criteria provided, single submitter clinical testing This missense variant replaces asparagine with aspartic acid at codon 139 of the MSH2 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with MSH2-related disorders in the literature. This variant has not been identified 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.
Ambry Genetics RCV001191976 SCV002626853 uncertain significance Hereditary cancer-predisposing syndrome 2020-02-12 criteria provided, single submitter clinical testing The p.N139D variant (also known as c.415A>G), located in coding exon 3 of the MSH2 gene, results from an A to G substitution at nucleotide position 415. The asparagine at codon 139 is replaced by aspartic acid, an amino acid with highly similar properties. This amino acid position is not well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
