Turner syndrome (TS) is a medical disorder that affects about 1 in every 2,500 girls. Although researchers don't know exactly what causes Turner syndrome, they do know that it's the result of a problem with a girl's chromosomes.
Girls with Turner syndrome are usually short in height. Those who aren't treated for short stature reach an average height of about 4 feet 7 inches (1.4 meters).
The good news is that when Turner syndrome is diagnosed while a girl is still growing, she can be treated with growth hormones to help her grow taller.
Most girls are born with two X chromosomes, but girls with Turner syndrome are born with only one X chromosome or they are missing part of one X chromosome. The effects vary widely among girls with Turner syndrome. It all depends on how many of the body's cells are affected by the changes to the X chromosome.
In addition to growth problems, Turner syndrome prevents the ovaries from developing properly, which affects a girl's sexual development and the ability to have children. Because the ovaries are responsible for making the hormones that control breast growth and menstruation, most girls with Turner syndrome will not go through all of the changes associated with puberty unless they get treatment for the condition. Nearly all girls with Turner syndrome will be infertile, or unable to become pregnant on their own.
A number of other health problems occur more often in girls with Turner syndrome, including kidney problems, high blood pressure, heart problems, overweight, hearing difficulties, diabetes, and thyroid problems. Some girls with the condition may experience learning difficulties, particularly in math. Many have a difficult time with tasks that require skills such as map reading or visual organization.
In addition to short stature and lack of sexual development, some of the other physical features commonly seen in girls with Turner syndrome are:
Because Turner syndrome can affect how a girl looks and develops, some girls may have problems with body image or self-esteem.
People with TS are all different. Some may have many physical differences and symptoms, whereas others experience only a few medical problems. With early and appropriate medical care and ongoing support, most people with TS can lead normal, healthy, and productive lives.
Girls with Turner syndrome are usually diagnosed either at birth or around the time they might be expected to go through puberty. If a baby girl has some of the signs of Turner syndrome, a doctor will usually order a special blood test called a karyotype. The test counts the number of chromosomes and can identify any that are abnormally shaped or have missing pieces.
In some cases, there are no recognizable signs that a girl has the condition until she reaches the age at which she would normally go through puberty.
If the karyotype blood test reveals that a girl has Turner syndrome, her doctor may order additional tests to check for problems with the kidneys, heart, hearing, and other problems that are often associated with Turner syndrome.
Because Turner syndrome is a condition that is caused by a chromosomal abnormality, there's no specific cure. However, scientists have developed a number of treatments that can help correct some of the problems associated with the condition — such as growth problems — and researchers are constantly looking into new forms of treatment.
Growth hormone treatment can improve growth and influence a girl's final adult height. In fact, in many cases, the treatment can help many girls with Turner syndrome reach a final height in the average range, especially if treatment is started early enough in childhood.
Another treatment for Turner syndrome is estrogen replacement, which helps the girl develop the physical changes of puberty, including breast development and menstrual periods. This treatment is often started when a girl reaches about age 12 or 13.
And a technique called in vitro fertilization can make it possible for some women with Turner syndrome to become pregnant. A donor egg can be used to create an embryo, which is then put into the uterus (womb) of the woman with Turner syndrome. With proper supportive care, the woman can carry the pregnancy to term and deliver a baby through the normal birth process.
Although people with Turner syndrome may have certain learning difficulties, the majority are able to attend regular school and classes and are generally able to:
If you have Turner syndrome, you know that it can affect you in several ways. But it's only a small part of your total physical, emotional, and intellectual self.
Here are some suggestions that can help you cope:
If you have a friend who has Turner syndrome, remember to respect her emotional and physical needs. For example, she may not always feel comfortable talking about her condition, so let her share only what she feels OK with.
You can also support your friend just by hanging out and doing things you enjoy together and by being a good listener if she turns to you for advice or comfort.
