What are two common PKU characteristics that PD's mom likely noticed in her son?

Question

Quizplus · Accepted Answer

Very light complexion and musty smelling urine are two common characteristics of PKU that PD's mom likely noticed in her son. PKU is a genetic disorder where the body is unable to break down phenylalanine, an amino acid found in many foods. When phenylalanine levels build up in the body, it can cause intellectual disability, behavioral problems, seizures, and other health issues. The musty odor in the urine is a result of the buildup of phenylalanine. The light complexion is due to a lack of melanin, which is also affected by phenylalanine levels in the body.

Answer: None of the other choices are correct.
 The other characteristics listed do not correspond with PKU. Dark skin pigmentation and foul breath are not associated with PKU, and neither are bowed legs and high pitched screeching. Bloody diarrhea and muscle paralysis are not commonly observed in PKU patients either. Severe insomnia and fatty stool are also not symptoms of PKU.
