Hereditary cancer-predisposing syndrome Uncertain:2
- -
The p.V200M variant (also known as c.598G>A), located in coding exon 1 of the AXIN2 gene, results from a G to A substitution at nucleotide position 598. The valine at codon 200 is replaced by methionine, an amino acid with highly similar properties. This amino acid position is 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. -
Oligodontia-cancer predisposition syndrome Uncertain:1Benign:1
This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease. -
This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 200 of the AXIN2 protein (p.Val200Met). This variant is present in population databases (rs752081909, gnomAD 0.003%). 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: 240026). 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. -
not provided Uncertain:1
Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge; This variant is associated with the following publications: (PMID: 15735151) -
AXIN2-related disorder Uncertain:1
The AXIN2 c.598G>A variant is predicted to result in the amino acid substitution p.Val200Met. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0026% of alleles in individuals of European (Non-Finnish) descent in gnomAD and has been reported in the ClinVar database as variant of uncertain significance (https://www.ncbi.nlm.nih.gov/clinvar/variation/240026/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
