A human mutation in Gabrg2 associated with generalized epilepsy alters the membrane dynamics of GABAA receptors.
Neuronal activity modulates the membrane diffusion of postsynaptic γ-aminobutyric acid (GABA)(A) receptors (GABA(A)Rs), thereby regulating the efficacy of GABAergic synapses. The K289M mutation in GABA(A)Rs subunit γ2 has been associated with the generalized epilepsy with febrile seizures plus (GEFS+) syndrome. This mutation accelerates receptor deactivation and therefore reduces inhibitory syn...
متن کاملTrafficking-deficient mutant GABRG2 subunit amount may modify epilepsy phenotype.
OBJECTIVE Genetic epilepsies and many other human genetic diseases display phenotypic heterogeneity, often for unknown reasons. Disease severity associated with nonsense mutations is dependent partially on mutation gene location and resulting efficiency of nonsense-mediated mRNA decay (NMD) to eliminate potentially toxic proteins. Nonsense mutations in the last exon do not activate NMD, thus pr...
متن کاملA splice-site mutation in GABRG2 associated with childhood absence epilepsy and febrile convulsions.
CONTEXT Missense mutations in the GABRG2 gene, which encodes the gamma 2 subunit of central nervous gamma-aminobutyric acid (GABA)(A) receptors, have recently been described in 2 families with idiopathic epilepsy. In one of these families, the affected individuals predominantly exhibited childhood absence epilepsy and febrile convulsions. OBJECTIVE To assess the role of GABRG2 in the genetic ...
متن کاملAuras in generalized epilepsy.
OBJECTIVE We studied the frequency of auras in generalized epilepsy (GE) using a detailed semistructured diagnostic interview. METHODS In this cross-sectional study, participants with GE were drawn from the Epilepsy Phenome/Genome Project (EPGP). Responses to the standardized diagnostic interview regarding tonic-clonic (grand mal) seizures were then examined. This questionnaire initially requ...
متن کاملGABRG2 rs211037 polymorphism and epilepsy: A systematic review and meta-analysis
PURPOSE The gamma-aminobutyric acid A receptor, gamma 2 (GABRG2) gene encodes the GABRγ2 protein, which has been implicated in susceptibility to epilepsy. Several studies have examined a possible link between the exonic GABRG2 rs211037 locus and susceptibility to febrile seizure (FS) and idiopathic generalized epilepsy (IGE), however results have been inconclusive. We therefore performed a syst...
