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]

Collection Method: clinical testing

The c.128A>C (p.N43T) alteration is located in exon 1 (coding exon 1) of the ADORA2B gene. This alteration results from a A to C substitution at nucleotide position 128, causing the asparagine (N) at amino acid position 43 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
