RCV002048385 | SCV002300259 | uncertain significance | Symmetrical dyschromatosis of extremities; Aicardi-Goutieres syndrome 6 | 2021-03-08 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (ExAC no frequency). 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. 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 glycine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with ADAR-related conditions. This sequence change replaces serine with glycine at codon 264 of the ADAR protein (p.Ser264Gly). The serine residue is weakly conserved and there is a small physicochemical difference between serine and glycine. |
