What is Down syndrome?

Down syndrome is a naturally occurring variation in the human genome, which contributes to the wide, rich range of human variability.

People with Down syndrome have extra genetic material. The scientific name for Down syndrome is Trisomy 21. In the cells of people with Down syndrome, the 21st chromosome, instead of being a pair of DNA threads, is actually a triplet.

Fascinating fact: March 21st is World Down Syndrome Day. March, the third month of the year, was chosen to acknowledge the unique triplet of chromosomes, and 21 was chosen to recognize the 21st chromosomal grouping.

At one point in history, Down syndrome was regarded as a disastrous diagnosis for a baby and a disappointing fate for their family. With increased knowledge and understanding, we now realize that Down syndrome is part of the rich tapestry of humankind.

Every person with Down syndrome lives Down syndrome differently, and every day there are positive and exciting developments in the Down syndrome world.

People who have Down syndrome and the people who know and love them are fortunate to experience first-hand the ways that diversity contributes to the beauty and synergy of human society.
