Genes affected

ADAR (HGNC:225): (adenosine deaminase RNA specific) This gene encodes the enzyme responsible for RNA editing by site-specific deamination of adenosines. This enzyme destabilizes double-stranded RNA through conversion of adenosine to inosine. Mutations in this gene have been associated with dyschromatosis symmetrica hereditaria. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2010]

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 892 of the ADAR protein (p.Arg892His). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with clinical features of Aicardi Goutieres syndrome (PMID: 23001123). ClinVar contains an entry for this variant (Variation ID: 39455). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt ADAR 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. -
