Genes affected

ADARB2 (HGNC:227): (adenosine deaminase RNA specific B2 (inactive)) This gene encodes a member of the double-stranded RNA adenosine deaminase family of RNA-editing enzymes and may play a regulatory role in RNA editing. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.96).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.919 is higher than 0.05.
