Chromosomes hold your DNA. Your DNA hold the plans for how your body grows and functions. There are 23 pairs of chromosomes. Down syndrome is a problem with pair 21. There is extra genetic material on pair 21. Each type of Down syndrome has its own genetic change:
Trisomy 21 is caused by:
An extra chromosome
Occurs when the cell divided in the egg or sperm
Mosaic Trisomy 21—extra chromosomes in some cells
Part of the chromosome breaks off and reattaches to another chromosome
There is no cure for Down syndrome. However, most people with Down syndrome can be an active part of the community. This includes school, work, and recreation. Some people with Down syndrome live with family. Others live with friends or on their own.
Support care can help with developmental challenges. Medical care may be needed for other complications.
Infants and Children
Infants with Down syndrome may take longer to feed. A child with Down syndrome will also start to talk, walk, and play later than others. Your medical team will help to check milestones for your child. Living at home and support therapy will help a child reach their full potential.
Medical care for related issues, like heart valves, may also be needed. Some may require surgery.
Learning opportunities may be increased with:
School programs designed to meet the child's unique needs.
Mainstreaming children into regular public school classes. Additional support can be added as needed.
