Labcorp Genetics (formerly Invitae), Labcorp RCV001925213 SCV002168870 uncertain significance Symmetrical dyschromatosis of extremities; Aicardi-Goutieres syndrome 6 2021-08-07 criteria provided, single submitter clinical testing 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: "Benign"; Align-GVGD: "Class C0". The tryptophan 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 variant is present in population databases (rs762094056, ExAC 0.001%). This sequence change replaces glycine with tryptophan at codon 163 of the ADAR protein (p.Gly163Trp). The glycine residue is weakly conserved and there is a large physicochemical difference between glycine and tryptophan.
