Quizplus · Accepted Answer

Down syndrome, also known as trisomy 21, is caused by an extra copy of chromosome 21. This extra genetic material increases the risk of developing various health problems, including leukaemia, cancer, Alzheimer's disease, and heart disease at an earlier age than usual. Individuals with Down syndrome have a higher likelihood of developing these conditions because of the presence of extra genetic material on chromosome 21.
