Arginase deficiency: This enzyme is involved in the final step of the urea cycle when arginine is cleaved to form urea and ornithine. Its deficiency results in argininemia, which is the least frequent of the urea cycle disorders. Hyperammonemia is not severe and the probable cause of neurotoxicity is arginine. The gene for this defect has been localized to chromosome band 6q23. Neonatal course is usually uneventful.
