<unk> , also called arginase deficiency, is an autosomal recessive urea cycle disorder where a deficiency of the enzyme arginase causes a build up of arginine and ammonia in the blood.
Ammonia, which is formed when proteins are broken down in the body, is toxic if levels become too high. The nervous system is especially sensitive to the effects of excess ammonia.
