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 GeneticsFeb 12, 2024The c.609T>G (p.I203M) alteration is located in exon 2 (coding exon 2) of the ADORA2B gene. This alteration results from a T to G substitution at nucleotide position 609, causing the isoleucine (I) at amino acid position 203 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
