Turner Syndrome
  • By Olivia Hoefling

2
What is Turner Syndrome?
  • Turner Syndrome is a genetic syndrome that
    effects every 1 in 2,500 females.
  • Most females are born with 2 x chromosomes, but
    females with Turners Syndrome are only born with
    one x chromosome (or part of one).

3
What are the physical symptoms?
  • A webbed neck (extra folds of skin)
  • A low hair line at the back of the neck
  • Drooping at the eyelids
  • Lower set ears
  • Abnormal bone development
  • Extra fluids in hands in feet
  • Short stature
  • Lack of sexual development

4
How do you inherit Turners?
  • Turners Syndrome is neither dominant or
    recessive.
  • It is caused by nondisjunction
  • When a pair of sex chromosomes fails to separate
    during the formation of an egg (or sperm)

5
Inheritance of Turners continued
  • As the embryo grows and the cells divide, every
    cell of the baby's body will be missing one of
    the X chromosomes.
  • Turners is not inherited from a parent because
    women with Turner syndrome are usually sterile
    and cannot have children.

6
How is Tuners diagnosed?
  • A doctor can easily suspect Turners by physical
    abnormalities, and blood tests can confirm this.
  • The point when Tuners can be diagnosed depends
    on the severity of the condition and how quickly
    it develops.

7
What is the life expectancy of someone with
Tuners?
  • Turners does not affect a persons life span.
  • However, Women with Tuner Syndrome are faced with
    health risks such as heart disease, diabetes,
    kidney problems, etc.

8
How can Tuner Syndrome be treated?
  • Growth hormones Can increase height.
  • Ex. Androgen
  • Estrogen Replacement Therapy Can promote
    development of secondary sexual characteristics
    as well as help maintain good bones and healthy
    tissue.

9
Are there any new treatments or research for
Tuners?
  • Women with Turner Syndrome are infertile.
  • However, with the use of reproductive
    technologies have been used to help woman with
    Turners become pregnant.
  • Ex. A donor egg can be used to create an embryo,
    which is carried by the Turner syndrome woman.

10
Statistics
  • 1 in every 2,500 live female births are affected
    by Turner Syndrome
  • 0.04 of U.S. population is affected.
  • 108,800 people in the U.S. are affected.

11
What is everyday life like for someone with
Turner Syndrome?
  • Depending on the severity of the condition, a
    woman with TS generally lives a normal life.
  • However, TS does involve more health risks
    (heart, kidney) so someone with TS has to have
    regular check ups and doctors appointments.
  • Cont

12
Everyday Life Continued
  • Though women with TS are just as intelligent as
    anyone else, some may experience learning
    difficulties.
  • Learning difficulties may include trouble in
    mathematics, spacial skills, and hearing problems
  • Continued

13
Everyday Life Continued
  • Women with TS have physical abnormalities, so
    this is something that they have to deal with in
    social situations every day.
  • This can greatly affect these girls self esteem
    and confidence so some sort of therapy is
    recommended.
