A 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 ...
Functional MRI with simultaneously acquired EEG (fMRI/EEG) can identify areas of signal change associated with interictal discharges. We report the fMRI/EEG study of a child with newly-diagnosed IGE, performed prior to the start of antiepileptic medication. The 7-years-old girl had very frequent absences, associated with eyelid myoclonia. Her EEG showed frequent, typical 3/sec discharges. Funct...
Commentary The study by Dlugos et al. adds to the important information on impaired attention, measured with the Continuous Performance task (CPT), in childhood absence epilepsy (CAE) that has emanated from the large multisite treatment study CAE by Glauser and colleagues (1–3). About 36% of CAE have impaired attention with errors of omission rather than of commission before treatment that impr...
BACKGROUND AND PURPOSE Since the γ-aminobutyric acid type-A receptor subunit γ2 gene (GABRG2) mutation was discovered in an Australian family with childhood absence epilepsy (CAE) and febrile convulsions, a few screening studies for the GABRG2 mutation have been conducted in sporadic individuals with CAE from other ethnic groups. The aim of this study was to determine whether or not the previou...
Absence seizures consist of bilateral spike-and-wave discharges (SWDs) occurring over widespread cortical and thalamic regions. In genetic models of absence epilepsy, recent in vivo investigations indicate that SWDs emerge first in the facial somatosensory cortex and then propagate via the corticothalamocortical loop. The specific involvement of this cortical region in ictogenic processes remai...
Aim of this study was to evaluate the effect of 5Hz-suprathreshold repetitive transcranial magnetic stimulation (rTMS) on the duration of the spike-and-wave discharges (SWDs) in a patient presenting idiopathic absence seizures. At the moment of the study the patient presented a mild blunting of consciousness due to the high frequency of absences and EEG recordings showed sub-continuous, general...
