RCV002949062 | SCV003276890 | uncertain significance | Symmetrical dyschromatosis of extremities; Aicardi-Goutieres syndrome 6 | 2024-01-07 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 72 of the ADAR protein (p.Arg72Trp). This variant is present in population databases (rs761657434, gnomAD 0.05%). This variant has not been reported in the literature in individuals affected with ADAR-related conditions. ClinVar contains an entry for this variant (Variation ID: 2066378). 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 tryptophan 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. |
| Ambry Genetics | RCV004068083 | SCV004854629 | likely benign | Inborn genetic diseases | 2023-11-04 | criteria provided, single submitter | clinical testing | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. |
