Transcript

  • 1. Down syndrome By Cody McPherson
  • 2. Down syndrome
    • A common chromosome disorder due to an extra chromosome number 21 (trisomy 21).
    • Down syndrome causes mental retardation, a characteristic facial appearance, and multiple malformations. It is associated with a major risk for heart malformations, a lesser risk of duodenal atresia (part of the small intestines is not developed), and a minor but still significant risk of acute leukemia .
