Phenylketonuria

PKU

PKU is an inborn error of phenylalanine metabolism that leads to toxic accumulation if untreated, causing intellectual disability and neurological harm. Newborn screening identifies affected infants so a low-phenylalanine diet and, in some cases, adjunct therapies can begin promptly. Lifelong metabolic monitoring remains important for optimal outcomes.
