Variant summary
Our verdict is Likely benign. Variant got -6 ACMG points: 0P and 6B. BP4_ModerateBS2
The NM_004655.4(AXIN2):c.2207C>T(p.Pro736Leu) variant causes a missense change. The variant allele was found at a frequency of 0.00000867 in 1,614,066 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/19 in silico tools predict 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. P736S) has been classified as Uncertain significance.

Submissions by phenotype
Oligodontia-cancer predisposition syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Nov 21, 2023 | This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 736 of the AXIN2 protein (p.Pro736Leu). This variant is present in population databases (rs778332146, gnomAD 0.01%). 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: 533186). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The leucine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Feb 03, 2022 | The p.P736L variant (also known as c.2207C>T), located in coding exon 8 of the AXIN2 gene, results from a C to T substitution at nucleotide position 2207. The proline at codon 736 is replaced by leucine, an amino acid with 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. - |
