Succinic semialdehyde dehydrogenase (SSADH) deficiency or 4-Hydroxybutyric Aciduria is an autosomal recessive inherited disorder of amma-aminobutyric acid (GABA) degradation. It is characterized by developmental delay, infantile-onset hypotonia, cognitive impairment language deficit, and ataxia. Epilepsy, aggression, Hyperkinetic behavior, hallucinations, and sleep disturbances have been descri...

Succinic semialdehyde dehydrogenase (SSADH) deficiency is a rare neurometabolic disorder characterized by defective degradation of gamma-aminobutyric acid (GABA), major inhibitory neurotransmitter the brain. Children with SSADH present motor mental delay, intractable seizures, infantile onset hypotonia, speech disturbances, extrapyramidal symptoms and ataxia. This wide spectrum results from inc...

2-Hydroxybutyric acid appears at high concentrations in situations related to deficient energy metabolism (e.g., birth asphyxia) and also in inherited metabolic diseases affecting the central nervous system during neonatal development, such as "cerebral" lactic acidosis, glutaric aciduria type II, dihydrolipoyl dehydrogenase (E3) deficiency, and propionic acidemia. The present study was carried...

Succinic semialdehyde dehydrogenase (SSADH) deficiency, a rare metabolic disorder of 4-aminobutyric acid degradation, has been identified in approximately 150 patients. Affected individuals accumulate large quantities of 4-hydroxybutyric acid, a compound with a wide range of neuropharmacological activities, in physiological fluids. As a first step in beginning an investigation of the molecular ...

4-Hydroxyacids are products of ubiquitously occurring lipid peroxidation (C(9), C(6)) or drugs of abuse (C(4), C(5)). We investigated the catabolism of these compounds using a combination of metabolomics and mass isotopomer analysis. Livers were perfused with various concentrations of unlabeled and labeled saturated 4-hydroxyacids (C(4) to C(11)) or 4-hydroxynonenal. All the compounds tested fo...
