Template:Stub Phenylketonuria is a genetic disorder that causes a deficiency in the enzyme phenylalanine hydroxylase. This enzyme normally metabolizes the amino acid phenylalanine into the amino acid tyrosine. If left untreated, the condition causes a build-up of phenylalanine in the tissues, which can lead to brain damage. Whilst it can be controlled by a diet low in phenylalanine and high in tyrosine if diagnosed early enough, there is currently no permanent cure.
