Down syndrome, also known as trisomy 21, is caused by an extra copy of chromosome 21 and is the most common chromosomal disorder in the human population occurring at an estimated rate of one in every 700 births. The number of babies born with Down syndrome continues to increase and individuals with Down syndrome are living longer than ever. In fact, the average life expectancy for an individual with Down syndrome has increased dramatically from 10 years old in the early 1900s to about 60 years old today.
