Summaries for GABRG2 Gene

Entrez Gene Summary for GABRG2 Gene

  • This gene encodes a gamma-aminobutyric acid (GABA) receptor. GABA is the major inhibitory neurotransmitter in the mammlian brain, where it acts at GABA-A receptors, which are ligand-gated chloride channels. GABA-A receptors are pentameric, consisting of proteins from several subunit classes: alpha, beta, gamma, delta and rho. Mutations in this gene have been associated with epilepsy and febrile seizures. Multiple transcript variants encoding different isoforms have been identified for this gene. [provided by RefSeq, Jul 2008]

GeneCards Summary for GABRG2 Gene

GABRG2 (Gamma-Aminobutyric Acid (GABA) A Receptor, Gamma 2) is a Protein Coding gene. Diseases associated with GABRG2 include epilepsy, childhood absence 2 and epilepsy, generalized, with febrile seizures plus, type 3. Among its related pathways are Akt Signaling and Apoptosis Pathway. GO annotations related to this gene include chloride channel activity and GABA-A receptor activity. An important paralog of this gene is GABRA4.

UniProtKB/Swiss-Prot for GABRG2 Gene

  • Component of the heteropentameric receptor for GABA, the major inhibitory neurotransmitter in the vertebrate brain. Functions also as histamine receptor and mediates cellular responses to histamine. Functions as receptor for diazepines and various anesthetics, such as pentobarbital; these are bound at a separate allosteric effector binding site. Functions as ligand-gated chloride channel.

Tocris Summary for GABRG2 Gene

  • GABAA receptors are members of the cys-loop family of ligand-gated ion channels, responsible for mediating the inhibitory effects of GABA alongside GABAB and GABAC receptors. They are pentameric proteins, consisting of 5 subunits belonging to different families (alpha1-6, beta1-3, gamma1-3, delta, pi, epsilon, rho, theta). The most abundant GABAA receptor in the mammalian brain consist of two copies each of alpha1 and beta2 with a single gamma2 subunits. GABAA receptors contain an integral chloride channel, and have modulatory sites for benzodiazepines, barbiturates, neurosteroids and ethanol.

Disorders for GABRG2 Gene

(2) OMIM Diseases for GABRG2 Gene (137164)


  • Epilepsy, childhood absence 2 (ECA2) [MIM:607681]: A subtype of idiopathic generalized epilepsy characterized by an onset at age 6-7 years, frequent absence seizures (several per day) and bilateral, synchronous, symmetric 3-Hz spike waves on EEG. Tonic-clonic seizures often develop in adolescence. Some individuals manifest febrile seizures. Absence seizures may either remit or persist into adulthood. {ECO:0000269 PubMed:11326275}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
  • Febrile seizures, familial, 8 (FEB8) [MIM:611277]: Seizures associated with febrile episodes in childhood without any evidence of intracranial infection or defined pathologic or traumatic cause. It is a common condition, affecting 2-5% of children aged 3 months to 5 years. The majority are simple febrile seizures (generally defined as generalized onset, single seizures with a duration of less than 30 minutes). Complex febrile seizures are characterized by focal onset, duration greater than 30 minutes, and/or more than one seizure in a 24 hour period. The likelihood of developing epilepsy following simple febrile seizures is low. Complex febrile seizures are associated with a moderately increased incidence of epilepsy. {ECO:0000269 PubMed:16924025}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Generalized epilepsy with febrile seizures plus 3 (GEFS+3) [MIM:611277]: 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. {ECO:0000269 PubMed:11326274}. Note=The disease is caused by mutations affecting the gene represented in this entry.
