Question

Quizplus · Accepted Answer

Phenylketonuria (PKU) is a genetic disorder that causes the body to be unable to metabolize phenylalanine, an amino acid found in many foods. This can lead to a build-up of phenylalanine, which can cause brain damage and intellectual disability. However, if PKU is diagnosed early and a restrictive diet low in phenylalanine is followed until early adulthood, the damage can be prevented or minimized. Therefore, the statement is true.
