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]

The c.1547G>A (p.R516H) alteration is located in exon 7 (coding exon 7) of the ADARB2 gene. This alteration results from a G to A substitution at nucleotide position 1547, causing the arginine (R) at amino acid position 516 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
