Treatment with amino acids in serine deficiency disorders.
Serine deficiency disorders are rare defects in the biosynthesis of the amino acid L-serine. At present two disorders have been reported: 3-phosphoglycerate dehydrogenase deficiency and 3-phosphoserine phosphatase deficiency. These enzyme defects lead to severe neurological symptoms such as congenital microcephaly and severe psychomotor retardation and in addition in patients with 3-phosphoglycerate dehydrogenase deficiency to intractable seizures. These symptoms respond to a variable degree to treatment with L-serine, sometimes combined with glycine. In this paper the current practice of amino acid treatment with L-serine and glycine in serine deficiency is reviewed.
