GABRG2 Gene (Protein Coding)

Gamma-Aminobutyric Acid Type A Receptor Subunit Gamma2

GC05P162000
GIFtS:
48
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 epi... See more...

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.

GeneCards Summary for GABRG2 Gene

GABRG2 (Gamma-Aminobutyric Acid Type A Receptor Subunit Gamma2) is a Protein Coding gene. Diseases associated with GABRG2 include Febrile Seizures, Familial, 8 and Developmental And Epileptic Encephalopathy 74. Among its related pathways are GABA receptor activation and Apoptosis Pathway. Gene Ontology (GO) annotations related to this gene include chloride channel activity and GABA-A receptor activity. An important paralog of this gene is GABRG1.

UniProtKB/Swiss-Prot Summary for GABRG2 Gene

  • Ligand-gated chloride channel which is a component of the heteropentameric receptor for GABA, the major inhibitory neurotransmitter in the brain (PubMed:2538761, PubMed:29950725). Plays an important role in the formation of functional inhibitory GABAergic synapses in addition to mediating synaptic inhibition as a GABA-gated ion channel (PubMed:23909897, PubMed:25489750, PubMed:27864268). The gamma2 subunit is necessary but not sufficient for a rapid formation of active synaptic contacts and the synaptogenic effect of this subunit is influenced by the type of alpha and beta subunits present in the receptor pentamer (By similarity). The alpha1/beta2/gamma2 receptor and the alpha1/beta3/gamma2 receptor exhibit synaptogenic activity (PubMed:23909897, PubMed:25489750). The alpha2/beta2/gamma2 receptor exhibits synatogenic activity whereas the alpha2/beta3/gamma2 receptor shows very little or no synaptogenic activity (By similarity). Functions also as histamine receptor and mediates cellular responses to histamine (By similarity).

Tocris Summary for GABRG2 Gene

  • GABAA receptors are members of the Cys-loop family of ligand-gated ion channels and, along with GABAB receptors, are responsible for mediating the inhibitory effects of GABA. They are pentameric proteins, consisting of five subunits belonging to different families.

GBRG2_HUMAN
  • Epileptic encephalopathy, early infantile, 74 (EIEE74) [MIM:618396]: A form of epileptic encephalopathy, a heterogeneous group of severe early-onset epilepsies characterized by refractory seizures, neurodevelopmental impairment, and poor prognosis. Development is normal prior to seizure onset, after which cognitive and motor delays become apparent. EIEE74 is an autosomal dominant form with onset in the first year of life. {ECO:0000269 PubMed:27864268}. Note=The gene represented in this entry is involved in disease pathogenesis.
  • 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 variants affecting the gene represented in this entry.
  • Febrile seizures, familial, 8 (FEB8) [MIM:607681]: 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 variants affecting the gene represented in this entry.
  • Generalized epilepsy with febrile seizures plus 3 (GEFS+3) [MIM:607681]: 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, ECO:0000269 PubMed:23708187}. Note=The disease is caused by variants affecting the gene represented in this entry.
