What Is Down Syndrome?

Down Syndrome

Say: down SIN-drohm

Down syndrome happens when a baby is born with an extra chromosome. This extra genetic material causes problems with the way the baby's body and brain develops.

People with Down syndrome have certain physical features, such as a flatter face and upward slanting eyes, and may have health problems, such as heart defects. Kids with Down syndrome usually have trouble learning, but they can go to regular schools and get jobs when they are older.
