WHAT IS

down syndrome? 

Down syndrome is a genetic disorder caused by the presence of all or part of a third copy of a chromosome (known as chromosome 21). It is typically associated with physical growth delays, mild to moderate intellectual/ developmental disabilities and characteristic facial features.

 

Down syndrome occurs in people of all races and economic levels, though older women have an increased chance of having a child with Down syndrome.
