WebPKU is an inborn error of metabolism transmitted by a recessive gene. PKU involves a mutation in DNA which causes inadequate production of an enzyme needed to metabolize phenylalanine, an amino acid. In utero, the fetus is unaffected because the maternal metabolism handles the excess phenylalanine.
