What is Phenylketonuria? Can It Be Cured?

Phenylketonuria is a genetic disorder where the body cannot metabolize phenylalanine normally, leading to excessive accumulation and affecting brain development. If diagnosed and treated early before symptoms appear, most patients can achieve normal intellectual levels. However, if left untreated or treated late, most patients will experience intellectual, motor, and language developmental delays. Early treatment leads to better outcomes.
