RCV000580351 | SCV000685300 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-09-13 | criteria provided, single submitter | clinical testing | This missense variant replaces leucine with gluatmine at codon 862 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. |
Invitae | RCV001853882 | SCV002115143 | uncertain significance | Hereditary nonpolyposis colorectal neoplasms | 2022-08-18 | 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 sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt MSH6 protein function. ClinVar contains an entry for this variant (Variation ID: 489986). 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 leucine, which is neutral and non-polar, with glutamine, which is neutral and polar, at codon 862 of the MSH6 protein (p.Leu862Gln). |
Ambry Genetics | RCV000580351 | SCV002739175 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-06-20 | criteria provided, single submitter | clinical testing | The p.L862Q variant (also known as c.2585T>A), located in coding exon 4 of the MSH6 gene, results from a T to A substitution at nucleotide position 2585. The leucine at codon 862 is replaced by glutamine, an amino acid with dissimilar properties. This amino acid position is conserved. 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. |
