RCV003112962 | SCV003790411 | uncertain significance | Symmetrical dyschromatosis of extremities; Aicardi-Goutieres syndrome 6 | 2022-08-02 | criteria provided, single submitter | clinical testing | This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 220 of the ADAR protein (p.Ala220Thr). This variant is present in population databases (no rsID available, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with ADAR-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Not Available"; Align-GVGD: "Class C0". The threonine 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. |
