A baby is typically born with 46 chromosomes. A baby with Down syndrome has a full or partial copy of chromosome 21.

The most common type of Down syndrome is trisomy 21, which accounts for 95% of all cases.

Less common types of Down syndrome are translocation (caused by rearranged chromosome material) and mosaicism (when there is a mixture of two types of cells). 

There are no known ways to prevent the condition during pregnancy and no known root causes, experts say.

"So, it’s no surprise that each year in October, we recognize Down Syndrome Awareness Month to raise public awareness about the condition and advocate for acceptance and inclusion of people with Down syndrome."

"People with Down syndrome still face stereotypes and myths, but they’ve shown time and again that the condition is just one part of who they are and doesn’t define them or limit their abilities," the statement continued.
