WebJun 5, 2016 · Phenylketonuria (PKU) is inherited in an autosomal recessive manner. In order to have PKU a person must have genetic changes (mutations) in both copies of the gene that causes this disorder PAH. A person who has PKU inherits one mutated gene for PKU from each parent. WebWhat causes phenylketonuria (PKU)? PKU is caused by mutations in the gene that helps make an enzyme called phenylalanine hydroxylase (pronounced fen-l-AL-uh-neen hahy-DROK-suh-leys ), or PAH.
