Gaba-transaminase Deficiency

Description

GABA-transaminase deficiency is characterized by neonatal or early infantile-onset encephalopathy, hypotonia, hypersomnolence, epilepsy, choreoathetosis, and accelerated linear growth. Electroencephalograms show burst-suppression, modified hypsarrhythmia, multifocal spikes, and generalized spike-wave. Severity varies, but most patients have profound developmental impairment and some patients die in infancy (summary by Koenig et al., 2017).
