Down Syndrome Overview Index

Featured: Down Syndrome Main Article

Down syndrome is a genetic disorder that is caused by an additional set of chromosomes in a developing fetus. Distinctive facial features, growth retardation, and decreased mental function and IQ are signs and symptoms of Down syndrome. Blood tests and ultrasound may be used to screen for Down syndrome but chromosome analysis of the fetus is needed to diagnose the condition. People with Down syndrome age more quickly and may develop Alzheimer's disease as young as age 40.
