Basic Facts

Every 1-800 people are affected with Down syndrome. This disease occurs when an extra chromosome 21 is present.


A person with Down syndrome could experience learning difficulties, poor muscular tone, increased heart risks, hearing loss, and a characteristic facial appearance. This can affect their daily life because they could not move or learn as other kids or adults do. Poor muscular tone and heart risks do not allow kids with Down syndrome to move and play as other kids and learning disabilities do not allow kids to communicate with others to the same extent. The life expectancy has grown from 25 in 1983 to 60 today. Many more studies are being done to prevent and cure Down syndrome.


Down syndrome occurs when there is an extra 21 chromosome present. There is no specific name for the gene being mutated.


Today, there is no cure for Down syndrome. However, you can do things to prevent symptoms of Down syndrome. You can do physical therapy, surgery for prevent eye problems, and surgery for throat and digestive problems.
