What is Down Syndrome?
Down syndrome occurs when an individual has a full or partial extra copy of chromosome 21. The additional genetic material alters the course of development and causes the characteristics associated with Down syndrome. A few of the common physical traits of Down syndrome are low muscle tone, small stature, an upward (almond) slant to the eyes, and a single deep crease across the center of the palm. Each person with Down syndrome is a unique individual and may possess these characteristics to different degrees, or not at all.
How common is Down Syndrome?
One in approximately 691 babies in the United States is born with Down syndrome. Approximately 400,000 Americans have Down syndrome and about 6,000 babies are born in the US each year. Approximately 4 million people worldwide have Down Syndrome.
