Down Syndrome
Get the facts on Down syndrome, a genetic disorder caused by an additional set of chromosomes in a developing fetus. Down syndrome signs and symptoms include distinctive facial features, growth retardation, and decreased mental function and IQ. 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. Sometimes people are diagnosed with mosaic Down syndrome, in which case they have more than one type of chromosomal makeup.
