This is a disorder caused by the deficiency of phenylalanine hydroxylase hence the patient is unable to digest phenylalanine . In severe cases, a build up of phenylalanine in the body can lead to brain damage and mental retardation. Sufferers of this disorder should be placed on a low phenylalanine diet to minimise effects of the condition.
