Quizplus · Accepted Answer

PKU (phenylketonuria) is a genetic disorder caused by a problem with a gene that controls the production of an enzyme called phenylalanine hydroxylase. This enzyme is needed to break down the amino acid phenylalanine, and without it, phenylalanine accumulates in the body and can cause brain damage and other health problems.
