Ambry Genetics | RCV000128983 | SCV000172871 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-04-19 | criteria provided, single submitter | clinical testing | The p.A64T variant (also known as c.190G>A), located in coding exon 1 of the MSH6 gene, results from a G to A substitution at nucleotide position 190. The alanine at codon 64 is replaced by threonine, an amino acid with similar properties. This amino acid position is not well 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. |
Invitae | RCV000531333 | SCV000624702 | uncertain significance | Hereditary nonpolyposis colorectal neoplasms | 2022-02-04 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (gnomAD no frequency). 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: 140804). This variant has not been reported in the literature in individuals affected with MSH6-related conditions. This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 64 of the MSH6 protein (p.Ala64Thr). |
