  1. Turner’s Syndrome By Audrey Dyer

  2. How is it inherited? • Most females have two X chromosomes • Girls with Turner’s syndrome are missing one or part of an X chromosome • In most cases, this is caused by disjunction: when a pair of sex chromosomes don’t separate during egg/sperm formation • It is not genetically passed down, because most females with Turner’s cannot have children

  3. What are the symptoms? • Ovaries don’t develop, which leads to inability to reach puberty and have children • Short stature, drooping eyelids • Webbed neck, low hairline • Extra fluid in hands and feet • Diabetes, high blood pressure, heart and kidney problems • Learning disabilities, especially with mathematics and tasks involving visual organization

  4. What are the statistics? • 1 per 2,500 live female births are affected in the United States • 71,000 women and girls living with TS today • Classified as a “rare disease”
