Disorders of GABA, glycine, serine, and proline

Research output: Chapter in Book/Report/Conference proceedingBook chapter

Abstract

Only for three of the known defects in the metabolism of the amino acidsGABA, glycine, serine, and proline has a more-or-less efficient treatment been reported: the GABA catabolic defect, succinic semialdehyde dehydrogenase deficiency (vigabatrin, causing substrate depletion by inhibition of GABA transaminase); the glycine catabolic defect, nonketotic hyperglycinemia (diet combined with benzoate and an N-methyl-d-aspartate, NMDA, receptor blocker); and 3- phosphoglycerate dehydrogenase deficiency (serine supplementation, in some patients to be associated with glycine supplementation). Notreatment has as yetbeen attempted in?1-pyrroline-5-carboxylate (P5CS) synthase deficiency; and the remaining six known defects probably have no clinical significance except for prolidase deficiency.
