Question

Quizplus · Accepted Answer

PKU (Phenylketonuria) is a genetic disorder that results in the inability to metabolize the amino acid phenylalanine. This can lead to a variety of neurological problems if not treated, including issues with myelination. However, it does not cause excessive myelination, nor does it involve myelin traveling into the soma or covering the dendrites in such a way that it stops communication. The primary issue is the toxic levels of phenylalanine that can inhibit normal brain development and function, including the formation of myelin.
