Phenylketonuria, an inborn error of metabolism inherited as an autosomal recessive trait (the PAH gene is located on chromosome 12q24), is caused by a deficiency or absence of the enzyme needed to metabolize the essential amino acid phenylalanine. Classic PKU is at one end of a spectrum of conditions known as .
