what does pku
Phenylketonuria (PKU) is a condition in which the body cannot break down one of the amino acids found in proteins. PKU is considered an amino acid condition because people with PKU cannot break down the amino acid called phenylalanine. If left untreated, PKU can cause brain damage or even death. However, if the condition is detected early and treatment is begun, individuals with PKU can lead healthy lives. Phenylketonuria is a condition with multiple forms, each of which have different treatments and outcomes. Classic phenylketonuria is only one form of the condition.
