RCV001910102 | SCV002184010 | uncertain significance | Singleton-Merten syndrome 1; Aicardi-Goutieres syndrome 7 | 2021-12-08 | criteria provided, single submitter | clinical testing | This variant is present in population databases (no rsID available, gnomAD 0.002%). This sequence change replaces serine, which is neutral and polar, with glycine, which is neutral and non-polar, at codon 205 of the IFIH1 protein (p.Ser205Gly). This variant has not been reported in the literature in individuals affected with IFIH1-related conditions. 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 glycine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. |
