DOWN SYDROME

WHAT DOWN SYNDROME IS

• A genetic chromosome 21 disorder causing developmental and intellectual delays
• Also called trisomy 21

CAUSES OF DOWN SYNDROME

• Research shows that three types of chromosomal changes can lead to Down syndrome
• Trisomy 21-child has three copies of chromome 21 in all cells
• Mosiac down syndrome-children have some cells with an extra copy of chromosome 21
• Translocation down syndrome-when part of chromosome 21 becomes attatched to another chromosome

there are no signs that a child will have Down syndrome during pregnancy. At birth, babies with Down syndrome usually have certain characteristic signs, including:
