Question

Quizplus · Accepted Answer

Phenylketonuria is caused by an inherited deficiency of phenylalanine hydroxylase, an enzyme that converts phenylalanine to tyrosine. Without this enzyme, phenylalanine and its byproducts build up in the blood and can cause brain damage and intellectual disability. The other options are all genetic disorders but are not related to phenylalanine metabolism.
