Gabrd — Gaba A Receptor Delta Subunit is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The GABRD gene encodes the delta subunit of the GABA-A receptor. Delta subunit-containing receptors are extrasynaptic and mediate tonic inhibition, important for maintaining baseline neuronal excitability. These receptors are highly sensitive to neurosteroids and ethanol, and may play a role in neuroprotection. They are primarily located in extrasynaptic regions and contribute to the regulation of neuronal network oscillations.

The GABA-A receptor is a ligand-gated chloride channel that mediates fast inhibitory neurotransmission in the central nervous system. The GABRD subunit contributes to the formation of heteromeric receptor complexes that determine the pharmacological properties, subcellular localization, and trafficking of the receptor.
GABA-A receptors typically consist of 2 alpha, 2 beta, and 1 gamma (or delta) subunits. The specific subunit composition determines:
| Disease | Inheritance | Mechanism |
|---|---|---|
| Juvenile Myoclonic Epilepsy | Various | Channel dysfunction |
| Peripheral Arterial Disease | Various | Altered inhibition |
| Various | Various | Seizure susceptibility |
| Various | Various | Neurodevelopmental |
While primarily associated with epilepsy and neurodevelopmental disorders, GABA-A receptor dysfunction may contribute to:
