About risk factors:

Risk factors for Down Syndrome are factors that do not seem to be a direct cause of the disease, but seem to be associated in some way. Having a risk factor for Down Syndrome makes the chances of getting a condition higher but does not always lead to Down Syndrome. Also, the absence of any risk factors or having a protective factor does not necessarily guard you against getting Down Syndrome. For general information and a list of risk factors, see the risk center.
