RCV000772563 | SCV000905743 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-08-21 | criteria provided, single submitter | clinical testing | This missense variant replaces arginine with glutamine at codon 495 of the MSH6 protein. Computational prediction suggests that this variant may have deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with MSH6-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 | RCV000772563 | SCV001172184 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-10-02 | criteria provided, single submitter | clinical testing | The p.R495Q variant (also known as c.1484G>A), located in coding exon 4 of the MSH6 gene, results from a G to A substitution at nucleotide position 1484. The arginine at codon 495 is replaced by glutamine, an amino acid with highly similar 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. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |

Invitae | RCV001856021 | SCV002257985 | uncertain significance | Hereditary nonpolyposis colorectal neoplasms | 2023-01-25 | 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 628220). This variant has not been reported in the literature in individuals affected with MSH6-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 495 of the MSH6 protein (p.Arg495Gln). |
