Question

Quizplus · Accepted Answer

Phenylketonuria (PKU) is a genetic disorder caused by a recessive gene that leads to the inability to metabolize phenylalanine, an amino acid. It is not treated with insulin, does not necessarily result in death by five years of age if managed properly, and is not caused by lipid accumulation in the nervous system.
