Down Syndrome, also known as trisomy 21, is a genetic disorder. The cause of this disorder is an extra 21st chromosome. People with Down's Syndrome are characterized by their differences in facial appearance, body structure, IQ, and physical growth.
There are many physical features common to people with Down Syndrome. Arms and legs are shorter, eyes are almond shaped, muscle tone is poor, the tongue protrudes, and one or both palms have a single crease (instead of a double crease).
The IQ of individuals with Down Syndrome is typically lower than average. They are frequently diagnosed with Mild to Moderate Mental Retardation. A small number of these individuals have Severe to Profound Mental Retardation.
