It occurs in babies who inherit two mutant genes for the enzyme phenylalanine hydroxylase (PAH). This enzyme normally breaks down molecules of the amino group acid phenylalanine that are in excess of the bodys needs for protein synthesis. Because we inherit two copies of the gene for the enzyme, both must be forged to produce the disease.

A laboratory test that measures how quickly an barb of phenylalanine is removed from the blood can distinguish a individual who has one PKU gene from a person who has none, further the person with one is perfectly healthy because the unmutated allele produces sufficiency of the enzyme. However, these heterozygous individuals are carriers of the disease. -------------------------------------------------------------------------------- The phenylalanine tolerance test.
