RCV001052680 | SCV001216903 | uncertain significance | not provided | 2023-12-08 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 296 of the MSH3 protein (p.Arg296Leu). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with MSH3-related conditions. ClinVar contains an entry for this variant (Variation ID: 848843). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. |
| Ambry Genetics | RCV002374915 | SCV002685319 | uncertain significance | Hereditary cancer-predisposing syndrome | 2024-04-24 | criteria provided, single submitter | clinical testing | The p.R296L variant (also known as c.887G>T), located in coding exon 5 of the MSH3 gene, results from a G to T substitution at nucleotide position 887. The arginine at codon 296 is replaced by leucine, an amino acid with dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. |
