Turner Syndrome

Turner syndrome is a genetic condition found in girls. Normally, girls have two X chromosomes (KRO ma som). Girls with Turner syndrome have one X chromosome. The second chromosome is either missing or formed the wrong way. Nothing you did before or during pregnancy caused Turner syndrome.

Common Features

Girls with Turner syndrome may:

  • Have normal intelligence
  • Be short
  • Have poor sense of direction
  • Have poor social skills
  • Mature late
  • Not be able to get pregnant naturally
  • Not have fine motor skills
   

Signs and Symptoms

Girls with Turner syndrome are at greater risk of having heart, kidney or thyroid problems.

Early signs of Turner syndrome:

  • Low set ears
  • Puffy hands and feet
  • Frequent ear infections
  • Short height
  • Arms that turn out slightly at elbows
  • Shortened bones in the hand
  • Low hairline
  • Several skin folds around the neck
 

Later signs of Turner syndrome:

  • Blood sugar problems
  • Curve in the spine
  • Delayed puberty
  • Thyroid problems
  • High blood pressure
  • Ovarian failure

Diagnosis

No one knows what causes Turner syndrome. Girls who are short for their age for no explained reason should have a karyotype (KAR e o type). A karyotype is a blood test to find out the total number of chromosomes and the sex chromosomes.

Treatment

Treatment for Turner syndrome includes regular checkups and hormone replacement therapy. There is no known cure. Treatment may be:

  • Growth hormone for short stature
  • Estrogen therapy for breast development and menstruation
  • Thyroid hormone replacement

Follow–up Appointments

  • Schedule regular follow-up appointments for your child with her doctor.
  • Write down all your questions as you think of them. Bring the list with you when you see the doctor. Be sure to call if you cannot keep the appointment.
