Names

Common Name: HTR2A Type: Gene
Chromosome: 13 (NC_000013.11) Locus: NG_013011.1 (HTR2A)
HUGO Symbol: HTR2A Full Name: 5-hydroxytryptamine receptor 2A

Description:
The HTR2A gene encodes the serotonin 2A receptor (5-HT2A), a G-protein-coupled receptor with considerable expression in various regions of the central nervous system (CNS). Ligand binding causes a conformation change that triggers signalling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of downstream effectors. Serotonin is a neurotransmitter critical for CNS development and function. It is also involved in the regulation of gastrointestinal motility and in haemostasis on platelets. Abnormal 5-HT2A receptor activity is associated with a number of psychiatric disorders and conditions, including depression, schizophrenia, and drug addiction. Genetic variance in HTRA2 gene associated with acute chest syndrome (ACS) in patients with sickle cell disease. ACS is a form of acute lung injury caused by vaso-occlusion within the pulmonary microvasculature. Etiologies either trigger vaso-occlusion (e.g., infection, asthma, hypoventilation) or are a result of vaso-occlusion (e.g., bone marrow and fat emboli).

Synonyms: 5-HT2A , HTR2
