Down syndrome is caused by the presence of an extra chromosome. Chromosomes are made up of genes that determine all the traits about your child. Children usually get 23 pairs of chromosomes from their parents. Kids with Down syndrome are born with an extra copy or fragment of chromosome 21 (which is why Down syndrome is also called “trisomy 21”).

This extra chromosome can cause delays in physical and mental development. But that doesn’t mean your child can’t live life to the fullest — especially when you have the right care team in your corner. Each child with Down syndrome is special and has unique needs. That’s why our specialists at Nemours work together — so your child can get all the care they need, all in one place.
