A little information about Down syndrome


Down syndrome is named after Doctor Langdon Down, who made new discoveries with the syndrome in 1866.  Down syndrome is also known as Trisomy 21 - meaning 3 copies of the 21st chromosome.

Down syndrome occurs when an individual has three, rather than two, copies of the 21st chromosome.  There is no known cause or prevention of this extra chromosome.  

The additional genetic material alters the course of development and causes the characteristics associated with Down syndrome.

Down syndrome is the most commonly occurring chromosomal condition. One in every 691 babies is born with Down syndrome.
  •  There are more than 400,000 people living with Down syndrome in the United States.

People with Down syndrome have an increased risk for certain medical conditions such as congenital heart defects, respiratory and hearing problems.  Many of these conditions are now treatable, so most people with Down syndrome lead healthy lives.

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.

All people with Down syndrome experience cognitive delays, but the effect is usually mild to moderate and is not indicative of the many strengths and talents that each individual possesses.

Quality educational programs, a stimulating home environment, good health care, and positive support from family, friends and the community enable people with Down syndrome to develop their full potential and lead fulfilling lives.

Researchers are making great strides in identifying the genes on Chromosome 21 that cause the characteristics of Down syndrome. Many feel strongly that it will be possible to improve, correct or prevent many of the problems associated with Down syndrome in the future.
