Phenylketonuria (PKU) is a genetic condition and there is no cure. A person will never outgrow the disorder. Years ago, doctors thought the people with PKU could go off their low-phenylalanine diet when they got older. However, doctors now strongly advise that people with PKU remain on a special diet for their entire lives.
