title: Genetic disorders of gamma-aminobutyric acid, glycine, and serine as causes of epilepsy.
abstract: Genetic disorders of gamma-aminobutyric acid (GABA), glycine, and serine metabolism and of the GABA and glycine receptors are causes of epilepsy with variable responsiveness to treatment. Pyridoxine-dependent convulsions and the GABA(A) receptor defects are pure epileptic disorders that respond well to treatment. The convulsions associated with 3-phosphoglycerate dehydrogenase deficiency can be completely abolished with amino acid therapy. Epilepsy is a major symptom in succinic semialdehyde dehydrogenase deficiency. The convulsions in these disorders are not responsive or are only partially responsive to treatment.
