Down Syndrome is a genetic chromosomal condition where a person is born with 47 chromosomes instead of the usual 46. Most cases of Down Syndrome are classified as trisomy 21 or nondisjunction where chromosome 21 is copied three times instead of two. There are also two other types of the condition called translocation and mosaicism. Down syndrome remains the most common chromosomal condition diagnosed in the United States. Each year, about 6,000 babies born in the United States have Down syndrome. This means that Down syndrome occurs in about 1 in every 700 babies. More than 400,000 people in the United States are living with Down Syndrome. An increase in education and family support have helped to enable those with Down Syndrome to live full lives. October is Down Syndrome Awareness month and March 21st is World Down Syndrome Day. Learn more about the causes, treatments and research for Down Syndrome on the website.
