  1. Turner syndrome Brian K. Colleen H.

  2. How does someone get turner syndrome? • Only in females  • Not inherited (just by chance) • The X chromosome is a much longer DNA molecule and contains most of the genes that are needed for cells to work. • Normally you would find one X chromosome, not a damaged one. When seen with only one X it is caused by the parents reproductive cell formation.

  3. There is no second X chromosome, so this person would have Turner syndrome. • All of the other chromosomes are intact, just the last pair determining the gender is either missing or damaged.

  4. Background: • In 1938. • A man named Henry Turner found that seven of his patients were suffering from dwarfism and had no sexual development. • All of these patients were between 15 and 23 years of age, so they should have had some sexual development. • He tried to treat them, but it was ineffective. • Ever since Turner tried to treat this, many more studies have broadened our knowledge with even more studies still going on.

  5. Symptoms/Treatment • Symptoms found in infants • Swollen hands and feet • Wide and webbed neck • Symptoms found in older females • Drooping eyelids • Dry eyes • Infertility • Short height • Treatment: An option is to take a growth hormone to make them taller.

  6. Interesting info • Linda Hunt, plays “Henrietta Lang” on NCIS: Los Angeles. • Chances of getting Turner Syndrome are 1 to 2,500.
