Aicardi-Goutieres syndrome 4 Uncertain:2
This sequence change replaces serine, which is neutral and polar, with phenylalanine, which is neutral and non-polar, at codon 97 of the RNASEH2A protein (p.Ser97Phe). 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 548457). This variant has not been reported in the literature in individuals affected with RNASEH2A-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.0009%). -
