Down syndrome is a genetic condition where a person has an extra chromosome, typically chromosome 21. This extra genetic material causes delays in physical and mental development. While the cause is unknown, the risk increases with the mother's age. Down syndrome can be detected before birth through screening tests. It cannot be prevented, but women have options for continuing or terminating the pregnancy if Down syndrome is detected. People with Down syndrome have characteristic physical features including a flat facial profile and inward curving small pinky finger.
