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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.019555002).
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00021 (32/152352) while in subpopulation AFR AF = 0.000722 (30/41572). AF 95% confidence interval is 0.000518. There are 0 homozygotes in GnomAd4. There are 19 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 410 of the ADAR protein (p.Glu410Gly). This variant is present in population databases (rs145652884, gnomAD 0.08%). 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: 235339). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt ADAR protein function with a negative predictive value of 80%. 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. -
