ADRA2C

Chr 4

adrenoceptor alpha 2C

Also known as: ADRA2L2, ADRA2RL2, ADRARL2, ALPHA2CAR

NCBI Gene: 152 ENSG00000184160 UniProt: P18825

ADRA2C encodes the alpha-2C adrenergic receptor, a G protein-coupled receptor that mediates presynaptic inhibition of neurotransmitter release from noradrenergic nerve terminals in sympathetic and central nervous systems, specifically modulating neurotransmission at lower levels of nerve activity. The gene is moderately constrained against loss-of-function variants (LOEUF 0.605), but specific disease associations and inheritance patterns for ADRA2C mutations have not been established in the current clinical literature.

ResearchSummary from RefSeq, UniProt

Alpha-2-adrenergic receptors are members of the G protein-coupled receptor superfamily. They include 3 highly homologous subtypes: alpha2A, alpha2B, and alpha2C. These receptors have a critical role in regulating neurotransmitter release from sympathetic nerves and from adrenergic neurons in the central nervous system. The mouse studies revealed that both the alpha2A and alpha2C subtypes were required for normal presynaptic control of transmitter release from sympathetic nerves in the heart and from central noradrenergic neurons. The alpha2A subtype inhibited transmitter release at high stimulation frequencies, whereas the alpha2C subtype modulated neurotransmission at lower levels of nerve activity. This gene encodes the alpha2C subtype, which contains no introns in either its coding or untranslated sequences. [provided by RefSeq, Jul 2008]

Interpreting a novel variant

This gene is strongly intolerant of loss-of-function variation in the population, so LoF variants warrant close attention. No curated mechanism annotation is available — see the mechanism card for the computational prediction and its caveats.Based on population constraint only.
