Gamma-glutamylcysteine synthetase deficiency

Gamma-glutamylcysteine synthetase deficiency is 1 of 4 diseases involving enzymes in the gamma-glutamyl cycle (Meister, 1974). The other 3 disorders are glutathione synthetase deficiency (231900), 5-oxoprolinuria, which is a severe or generalized form of glutathione synthetase deficiency (266130), and gamma-glutamyl transpeptidase deficiency (231950). All except gamma-glutamyl transpeptidase deficiency are accompanied by hemolytic anemia (Larsson and Anderson, 2001).
