RCV001064011 | SCV001228883 | uncertain significance | not provided | 2023-03-17 | criteria provided, single submitter | clinical testing | In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The valine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 858187). This variant has not been reported in the literature in individuals affected with MSH3-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.01%). This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 537 of the MSH3 protein (p.Ile537Val). |
| Ambry Genetics | RCV004030519 | SCV005018637 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-10-06 | criteria provided, single submitter | clinical testing | The p.I537V variant (also known as c.1609A>G), located in coding exon 11 of the MSH3 gene, results from an A to G substitution at nucleotide position 1609. The isoleucine at codon 537 is replaced by valine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
