Down Syndrome

​People with down syndrome have a few things that people without down syndrome don't. They have a few characteristics that make them unique and special in there own way. One of the things they have is brush field spots on their eyes. Also if you look at the palm of your hand, right before your fingers, there are two lines going across, but for people with down syndrome they have only one line going across. These characteristics are caused by the extra chromosomes in their body.
