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 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.

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -
