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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 14, 2023The c.577C>T (p.P193S) alteration is located in exon 2 (coding exon 2) of the ADORA2B gene. This alteration results from a C to T substitution at nucleotide position 577, causing the proline (P) at amino acid position 193 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
