Congenital microcephaly, intractable seizures and severe psycho-motor retardation characterize 3-phosphoglycerate dehydrogenase (3-PGDH) deficiency, a disorder of L-serine biosynthesis. The enzyme defect results in low concentrations of serine and to a variable degree of glycine in plasma and cerebrospinal fluid. Short-term beneficial effects have been reported of oral treatment with the deficient amino acids. In this paper, we report the first follow-up data of amino acid therapy in five patients treated for 3–7.5 years. Different treatment regimes were used, but a favourable response to amino acids was observed in all patients. A major reduction in seizure frequency occurred in all patients; two patients became free of seizures. Amino acids were well tolerated and no adverse effects were documented. A progress of psychomotor development was only observed in one patient, diagnosed early and treated with a high dosage of L-serine. A favourable outcome of 3-PGDH deficiency depends on early diagnosis and treatment.
