Phenylketonuria develops due to presence of
WebPhenylketonuria (PKU) is a rare metabolic disorder. Children with PKU can’t process an amino acid called phenylalanine. Phenylalanine is in many common foods. It helps the body make protein. It's also important for brain growth. It's normally changed to tyrosine, which helps create all of the body's proteins. WebPhenylketonuria is a disorder of amino acid metabolism that occurs in infants born without the ability to normally break down an amino acid called phenylalanine. Phenylalanine, which is toxic to the brain, builds up in the blood. Phenylketonuria occurs when parents pass the defective gene that causes this disorder on to their children.
