GABAA receptor γ2 subunit
Role:  Childhood absence epilepsy (CAE, ECA), a subtype of idiopathic generalized epilepsy (EIG; 600669), is characterized by a sudden and brief impairment of consciousness that is accompanied by a generalized, synchronous, bilateral, 2.5- to 4-Hz spike and slow-wave discharge (SWD) on EEG. Seizure onset occurs between 3 and 8 years of age and seizures generally occur multiple times per day. About 70% of patients experience spontaneous remission of seizures, often around adolescence. Febrile seizures may occur. There are no structural neuropathologic findings in patients with ECA
Side effects:  Generalized tonic-clonic seizures often develop in adolescence
