The clinical features of argininemia in two cousins included hyperactivity, spasticity, ataxia, retardation, and repeated attacks of hyperammonemia. Study of a large kindred suggests that arginase-deficiency is transmitted as a Mendelian recessive. Treatment with an essential amino acid mixture with the total nitrogen intake limited to the requirement, controlled the hyperammonemia, reduced the plasma arginine level, and permitted a marked clinical improvement. There has been a significant increase in intelligence levels; the previously retarded children are now approaching the normal range of function.
