Down syndrome, also called trisomy 21, occurs when babies are born with an extra 21st chromosome. Individuals with Down syndrome typically have a flattened nose, tightened eyelids, low-set ears, and short neck. They also are short in stature have short and broad hands, and tend to have heart problems and a shortened life span. Also, people with Down syndrome have mental retardation with IQs typically between 25 and 50. In 95 percent of Down syndrome cases, the extra 21st chromosome exists because the 21st chromosome pair did not separate normally when the egg was formed. The number one risk factor for giving birth to a Down syndrome child is to become pregnant after age 35.
