Question

Quizplus · Accepted Answer

PKU (phenylketonuria) is a genetic condition in which the body cannot break down an amino acid called phenylalanine, which can lead to intellectual disability if left untreated. The condition can be managed by adhering to a strict low phenylalanine diet, which can prevent intellectual disability from occurring. However, if left untreated, PKU can result in intellectual disability. Being on a vegetarian diet is not a cause of PKU.
