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]

The c.125C>T (p.T42I) alteration is located in exon 1 (coding exon 1) of the ADORA2B gene. This alteration results from a C to T substitution at nucleotide position 125, causing the threonine (T) at amino acid position 42 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
