    PKU Directory

    PKU, or phenylketonuria, is a genetic disorder that blocks the body's ability to break down an amino acid called phenylalanine, which is found in protein. The build-up of phenylalanine can cause brain damage. Today, all babies born in the United States are routinely screened for PKU (phenylketonuria), at birth. Follow the links below to find WebMD's comprehensive coverage about how PKU is inherited, what the symptoms are, how to treat it, and much more.
