Submissions by phenotype
Oligodontia-cancer predisposition syndrome Uncertain:1
This sequence change replaces tyrosine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 224 of the AXIN2 protein (p.Tyr224Cys). This variant is present in population databases (no rsID available, gnomAD 0.002%). 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: 464637). 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 expected to disrupt AXIN2 protein function with a positive 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. -
Colorectal cancer Uncertain:1

Hereditary cancer-predisposing syndrome Uncertain:1
The p.Y224C variant (also known as c.671A>G), located in coding exon 1 of the AXIN2 gene, results from an A to G substitution at nucleotide position 671. The tyrosine at codon 224 is replaced by cysteine, an amino acid with highly dissimilar 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. -
