Question

Quizplus · Accepted Answer

PKU is a genetic metabolic disorder in which the body is unable to break down the amino acid phenylalanine, leading to a buildup of toxic byproducts. This can cause intellectual disabilities if left untreated. The most effective treatment is a life-long special diet low in phenylalanine to prevent the accumulation of harmful byproducts. PKU does not go away in late childhood, and it is not the only known genetically determined metabolic disorder.
