Question

Quizplus · Accepted Answer

Abnormal amyloid proteins are found in the brains of people with Down syndrome. This is because Down syndrome is associated with the overproduction of amyloid precursor protein (APP), which can lead to the formation of beta-amyloid plaques in the brain. Fragile-X syndrome, phenylketonuria, and fetal alcohol syndrome do not involve abnormal amyloid protein accumulation in the brain.
