Variant summary

Our verdict is Benign. Variant got -19 ACMG points: 1P and 20B. PP2BP4_StrongBP6_Very_StrongBA1

The NM_001111.5(ADAR):​c.298A>G​(p.Arg100Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.999 in 1,609,886 control chromosomes in the GnomAD database, including 803,673 homozygotes. In-silico tool predicts a benign outcome for this variant. 14/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R100A) has been classified as Uncertain significance.

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 made for transcript

Verdict is Benign. Variant got -19 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), ADAR. . Gene score misZ 2.2714 (greater than the threshold 3.09). Trascript score misZ 3.4067 (greater than threshold 3.09). GenCC has associacion of gene with dyschromatosis symmetrica hereditaria, Aicardi-Goutieres syndrome, Aicardi-Goutieres syndrome 6, Leigh syndrome, familial infantile bilateral striatal necrosis.
BP4
Computational evidence support a benign effect (MetaRNN=1.1511453E-6).
BP6
Variant 1-154602344-T-C is Benign according to our data. Variant chr1-154602344-T-C is described in ClinVar as [Benign]. Clinvar id is 500335.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BA1
GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.994 is higher than 0.05.
