Down Syndrome Awareness Month

Today starts the beginning of national Down syndrome awareness month. So I thought I would start with a few facts about Down syndrome.
-Down syndrome occurs when an individual has three, rather than two, copies of the 21st chromosome. This additional genetic material alters the course of development and causes the characteristics associated with Down syndrome.
-Down syndrome is the most commonly occurring chromosomal condition. One in every 733 babies is born with Down syndrome.
-There are more than 400,000 people living with Down syndrome in the United States.
