WebNon-PKU hyperphenylalaninemia, also called variant phenylketonuria, is an inherited (genetic) condition that prevents the body from processing proteins correctly. Your body breaks down the protein that you eat into parts called amino acids. Your body then uses those amino acids to make other proteins that it needs to function. WebPhenylketonuria (PKU) is a genetic condition that causes elevated levels of a substance called phenylalanine to build up in your body.
