RCV000640247 | SCV000761836 | uncertain significance | Oligodontia-cancer predisposition syndrome | 2025-01-17 | criteria provided, single submitter | clinical testing | This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 490 of the AXIN2 protein (p.Ala490Val). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with AXIN2-related conditions. ClinVar contains an entry for this variant (Variation ID: 533219). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt AXIN2 protein function with a negative predictive value of 80%. 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 | RCV001011728 | SCV001172085 | uncertain significance | Hereditary cancer-predisposing syndrome | 2024-03-12 | criteria provided, single submitter | clinical testing | The p.A490V variant (also known as c.1469C>T), located in coding exon 5 of the AXIN2 gene, results from a C to T substitution at nucleotide position 1469. The alanine at codon 490 is replaced by valine, 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. |
