Genes affected
ADORA2B (HGNC:264): (adenosine A2b receptor) This gene encodes an adenosine receptor that is a member of the G protein-coupled receptor superfamily. This integral membrane protein stimulates adenylate cyclase activity in the presence of adenosine. This protein also interacts with netrin-1, which is involved in axon elongation. The gene is located near the Smith-Magenis syndrome region on chromosome 17. [provided by RefSeq, Jul 2008]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 26, 2022The c.409G>A (p.G137R) alteration is located in exon 2 (coding exon 2) of the ADORA2B gene. This alteration results from a G to A substitution at nucleotide position 409, causing the glycine (G) at amino acid position 137 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
