Nota bene: Urea cycle disorders are characterized by the triad of hyperammonemia, encephalopathy, and respiratory alkalosis. Five disorders involving different defects in the biosynthesis of the enzymes of the urea cycle have been described: ornithine transcarbamylase deficiency (MIM.311250), carbamyl phosphate synthetase deficiency (MIM.237300), argininosuccinate synthetase deficiency, or citrullinemia (MIM.215700), argininosuccinate lyase deficiency, and arginase deficiency (MIM.207800).
