Quizplus · Accepted Answer

Chromosome 21 was the first chromosome linked to the onset of Alzheimer's disease. This is because individuals with Down syndrome, who have an extra copy of chromosome 21, often develop Alzheimer's disease at an earlier age. Further research has also found that specific genes located on chromosome 21, such as amyloid precursor protein (APP), may be involved in the development of Alzheimer's disease in individuals without Down syndrome.
