Down syndrome is an illness that claims a lot of people, but some people may wonder exactly what down syndrome is. There actually 3 types of Down syndrome, the most common kind that 95% of the people with Down syndrome have is called Trisomy 21. It is when a person is born with 47 chromosomes instead of the usual 46 because of an error in the development of the cells in the body. The name Trisomy 21 came from the fact that the extra gene is found in the 21st pair of chromosomes, the 47th chromosome. Because of this imbalance in the chromosomes, the extra gene changes the development of the brain and body of the infant. Four percent of people with Down syndrome have Translocation which is when the extra gene broke off and attached itself to another one. Lastly, the one percent of people who live with Down syndrome have what’s called Mosaicism is where only some of the cells have Trisomy 21. It is estimated that 1.3 out of 1000 births result in a baby being born with Down syndrome, the risk for a baby with down syndrome being born is higher if the mother is over 35 years old. Each year 5,000 babies are born with Down syndrome, in the U.S. alone there are an estimated 250,000 people who have Down syndrome.

They have small features on their bodies and one palmar crease on one or both hands. They will also have a high social intelligence.
