First Trimester Screening & Non-Invasive Prenatal Testing - Causes and Risk Factors

Down syndrome arises due to the presence of extra genetic material (known as a “chromosome”) in a person’s cells. This additional genetic material affects the way the brain and body develop.

Women at higher risk of having a baby with Down syndrome include those:
  • Who are older when they get pregnant
  • Have a previous child with Down syndrome
  • Have siblings with Down syndrome
However, anyone can have a baby with Down syndrome, including women who are younger or who have no history of Down syndrome in the family.
