Variant summary
Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4
The NM_004655.4(AXIN2):c.602G>A(p.Arg201Lys) variant causes a missense change. The variant allele was found at a frequency of 0.00000124 in 1,614,062 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R201G) has been classified as Uncertain significance.

Oligodontia-cancer predisposition syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | May 02, 2022 | This sequence change replaces arginine, which is basic and polar, with lysine, which is basic and polar, at codon 201 of the AXIN2 protein (p.Arg201Lys). This variant is present in population databases (no rsID available, gnomAD 0.0009%). 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: 533206). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). 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. - |
Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | May 13, 2023 | The p.R201K variant (also known as c.602G>A), located in coding exon 1 of the AXIN2 gene, results from a G to A substitution at nucleotide position 602. The arginine at codon 201 is replaced by lysine, an amino acid with highly similar properties. This amino acid position is conserved. 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. - |
