Abstract

3-Phosphoglycerate dehydrogenase (3-PGDH) deficiency is an inborn error of serine biosynthesis. Patients are affected with congenital microcephaly, psychomotor retardation, and intractable seizures. The effects of oral treatment with amino acids were investigated in 2 siblings. L-Serine up to 500 mg/kg/day was not sufficient for seizure control. Addition of glycine 200 mg/kg/day resulted in complete disappearance of seizures. Electroencephalographic abnormalities gradually resolved after 6 months. We conclude that 3-PGDH can be treated effectively by a combination of L-serine and glycine.
