Invitae RCV000809847 SCV000950027 uncertain significance Hereditary nonpolyposis colorectal neoplasms 2022-12-04 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. 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 not expected to disrupt MSH6 protein function. ClinVar contains an entry for this variant (Variation ID: 584612). 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 alanine, which is neutral and non-polar, with glycine, which is neutral and non-polar, at codon 182 of the MSH6 protein (p.Ala182Gly).
Ambry Genetics RCV002343578 SCV002653834 uncertain significance Hereditary cancer-predisposing syndrome 2020-02-13 criteria provided, single submitter clinical testing The p.A182G variant (also known as c.545C>G), located in coding exon 3 of the MSH6 gene, results from a C to G substitution at nucleotide position 545. The alanine at codon 182 is replaced by glycine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. 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.
