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

Verdict is Pathogenic. Variant got 11 ACMG points.

• PM1: In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 8 uncertain in NM_001111.5
• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the ADAR gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 16 curated pathogenic missense variants (we use a threshold of 10). The gene has 30 curated benign missense variants. Gene score misZ: 2.2714 (below the threshold of 3.09). Trascript score misZ: 3.4067 (above the threshold of 3.09). GenCC associations: The gene is linked to dyschromatosis symmetrica hereditaria, Aicardi-Goutieres syndrome, Aicardi-Goutieres syndrome 6, Leigh syndrome, familial infantile bilateral striatal necrosis.
• PP3: Splicing scoreres supports a deletorius effect: Scorers claiming Pathogenic: dbscSNV1_ADA, dbscSNV1_RF. No scorers claiming Uncertain. Scorers claiming Benign: max_spliceai.
• PP5: Variant 1-154588125-C-G is Pathogenic according to our data. Variant chr1-154588125-C-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 3239322.Status of the report is criteria_provided_single_submitter, 1 stars.
