2-hydroxyglutaric aciduria

Combined D-2- and L-2-hydroxyglutaric aciduria (D-2-HG and L-2-HG) is an autosomal recessive neurometabolic disorder characterized by neonatal-onset encephalopathy with severe muscular weakness, intractable seizures, respiratory distress, and lack of psychomotor development resulting in early death. Brain imaging shows abnormalities including enlarged ventricles, delayed myelination, and germinal layer cysts (summary by Muntau et al., 2000).
