What is the official name of the GABRD gene?
The official name of this gene is “gamma-aminobutyric acid (GABA) A receptor, delta.”
GABRD is the gene's official symbol. The GABRD gene is also known by other names, listed below.

What is the normal function of the GABRD gene?
- From NCBI Gene:
Gamma-aminobutyric acid (GABA) is the major inhibitory neurotransmitter in the mammalian brain where it acts at GABA-A receptors, which are ligand-gated chloride channels. Chloride conductance of these channels can be modulated by agents such as benzodiazepines that bind to the GABA-A receptor. The GABA-A receptor is generally pentameric and there are five types of subunits: alpha, beta, gamma, delta, and rho. This gene encodes the delta subunit. Mutations in this gene have been associated with susceptibility to generalized epilepsy with febrile seizures, type 5. Alternatively spliced transcript variants have been described for this gene, but their biological validity has not been determined. [provided by RefSeq, Jul 2008]
- From UniProt:
GABA, the major inhibitory neurotransmitter in the vertebrate brain, mediates neuronal inhibition by binding to the GABA/benzodiazepine receptor and opening an integral chloride channel.
How are changes in the GABRD gene related to health conditions?
- Genetics Home Reference provides information about juvenile myoclonic epilepsy, which is associated with changes in the GABRD gene.
- UniProt provides the following information about the GABRD gene's known or predicted involvement in human disease.
Generalized epilepsy with febrile seizures plus 5 (GEFS+5): A rare autosomal dominant, familial condition with incomplete penetrance and large intrafamilial variability. Patients display febrile seizures persisting sometimes beyond the age of 6 years and/or a variety of afebrile seizure types. This disease combines febrile seizures, generalized seizures often precipitated by fever at age 6 years or more, and partial seizures, with a variable degree of severity. Disease susceptibility is associated with variations affecting the gene represented in this entry.
Epilepsy, idiopathic generalized 10 (EIG10): A disorder characterized by recurring generalized seizures in the absence of detectable brain lesions and/or metabolic abnormalities. Generalized seizures arise diffusely and simultaneously from both hemispheres of the brain. Disease susceptibility is associated with variations affecting the gene represented in this entry.
Juvenile myoclonic epilepsy 7 (EJM7): A subtype of idiopathic generalized epilepsy. Patients have afebrile seizures only, with onset in adolescence (rather than in childhood) and myoclonic jerks which usually occur after awakening and are triggered by sleep deprivation and fatigue. Disease susceptibility is associated with variations affecting the gene represented in this entry.
- NCBI Gene lists the following diseases or traits (phenotypes) known or believed to be associated with changes in the GABRD gene.
- Epilepsy, idiopathic generalized 10
- OMIM.org, a catalog designed for genetics professionals and researchers, provides the following information about the GABRD gene and its association with health conditions.
