Genes affected

ADRA2B (HGNC:282): (adrenoceptor alpha 2B) This intronless gene encodes a seven-pass transmembrane protein. This protein is a member of a subfamily of G protein-coupled receptors that regulate neurotransmitter release from sympathetic nerves and from adrenergic neurons in the central nervous system.
