ABSTRACT
Serine deficiency disorders are a new group of neurometabolic diseases resulting from a deficiency in one of the three enzymes in the biosynthetic pathway of L-serine. Deficiency of the enzyme 3-phosphoglycerate dehydrogenase (3-PGDH), which catalyzes the first step in the biosynthetic pathway, leads to congenital microcephaly, severe psychomotor retardation, and intractable seizures. We report a 4 1/2-year-old boy who presented with congenital microcephaly, psychomotor retardation, hypertonia, strabismus, and drug-resistant seizures due to 3-PGDH deficiency. His seizures responded to L-serine and glycine supplementation only. This potentially treatable disease should be borne in mind in patients with congenital microcephaly, psychomotor retardation and seizures. A timely diagnosis based on the detection of low cerebrospinal fluid levels of L-serine and glycine is expected to further increase the success of L-serine and glycine supplementation in these patients.
