Turner Syndrome Clinic

What is Turner syndrome?

Turner syndrome is a genetic condition. It occurs when a girl is born with only 1 X chromosome instead of 2 or is missing part of an X chromosome. About 1 in every 2,000 girls has Turner syndrome.

Girls with Turner syndrome tend to be shorter than average, and most do not go through typical sexual development (puberty). They may have other health problems, such as: 

  • Congenital heart defects: About half of the girls with Turner syndrome also have some type of structural problem with their heart, such as bicuspid aortic valve or coarctation of the aorta.
  • High blood pressure (hypertension)
  • Thyroid problems (hypothyroidism)
  • Hearing and vision problems
  • Structural differences in the kidneys
  • Problems with the fat levels (lipids) in the blood
  • Lymphedema (especially in the feet and hands)
  • Differences in bone development
  • Learning difficulties, but otherwise usually have normal intelligence 

As an adult, they also have a higher-than-average risk of diabetes, obesity, coronary artery disease and stroke.

There is no cure for Turner syndrome. But with appropriate medical care, girls with this condition live full and productive lives.
