RCV003788314 | SCV004569879 | uncertain significance | Singleton-Merten syndrome 1; Aicardi-Goutieres syndrome 7 | 2022-05-12 | criteria provided, single submitter | clinical testing | This variant has not been reported in the literature in individuals affected with IFIH1-related conditions. This sequence change replaces isoleucine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 46 of the IFIH1 protein (p.Ile46Met). This variant is not present in population databases (gnomAD no frequency). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). 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. |
