Phenylketonuria (PKU):

Question

Quizplus · Accepted Answer

PKU is a genetic disorder that involves the inability to metabolize phenylalanine, an amino acid found in many foods containing protein. If left untreated, build-up of phenylalanine can lead to brain damage and intellectual disability. Therefore, individuals with PKU need to follow a special diet low in phenylalanine to prevent these adverse effects. Option A is not true, as PKU increases the risk of brain damage, not resistance against it. Option B is not true, as PKU is a genetic disorder that is inherited. Option D is not entirely accurate, as the IQ range for individuals with PKU can vary and is not limited to 75-100.
