    • Down syndrome occurs when an individual has three, rather than two, copies of the 21st chromosome. This additional genetic material alters the course of development and causes the characteristics associated with Down syndrome.

    • There are more than 400,000 people living with Down syndrome in the United States.

    • A few of the common physical traits of Down syndrome are low muscle tone, small stature, an upward slant to the eyes, and a single deep crease across the center of the palm. Every person with Down syndrome is a unique individual and may possess these characteristics to different degrees or not at all.

    • People with Down syndrome attend school, work, participate in decisions that affect them, and contribute to society in many wonderful ways.
