Causes

Why It HappensThe reason for Down

Syndrome is that there is an extra chromosome. This results in 47 chromosomes instead of 46. When someone has Down Syndrome, instead of having three copies of chromosome 21 instead of the two that they are supposed to have. The cause of the extra chromosome has not been discovered.

How It Affects Other Systems

Down Syndrome affects other systems by putting you at risk for diseases that affect various systems of the body. An example of this is that Down Syndrome may put one at risk for congenital heart failure and in that way affects the cardiovascular system.
