Down syndrome (DS) results from having extra genetic material on chromosome 21. The effects of DS can differ in their severity. Most individuals with DS have some degree of intellectual disability and developmental delay. The heart, thyroid, hearing, and vision problems often present in individuals with DS can be treated. Research and early interventions are now leading to much better quality of life for children and adults with this condition.
