Gamma-aminobutyric acid receptor subunit delta

Gene

GABRD

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

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.

Involvement in diseasei

Generalized epilepsy with febrile seizures plus 5 (GEFS+5)1 Publication

Disease susceptibility is associated with variations affecting the gene represented in this entry.

Disease descriptionA 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.

Epilepsy, idiopathic generalized 10 (EIG10)

Disease susceptibility is associated with variations affecting the gene represented in this entry.

Disease descriptionA 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.

Juvenile myoclonic epilepsy 7 (EJM7)

Disease susceptibility is associated with variations affecting the gene represented in this entry.

Disease descriptionA 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.
