Turner syndrome is a genetic disorder that includes a broad spectrum of features that vary in individuals. Common features include short stature and loss of ovarian function. The loss of ovarian function usually leads to infertility and inhibited sexual development.
Turner syndrome only occurs in girls and women. Females normally have 2 X chromosomes. Turner syndrome is most commonly caused by a missing X chromosome. It is usually sporadic, meaning that it is not inherited from a parent.
In rare cases, a parent silently carries rearranged chromosomes that can result in Turner syndrome in a daughter. This is the only situation in which Turner syndrome is inherited.
The main symptoms of this syndrome include:
Other physical features can include:
Other health conditions that can occur include:
Depending on its severity, Turner syndrome may first be diagnosed in infancy, childhood, or adolescence.
The doctor will ask about your symptoms and medical history. A physical exam will be done. A gynecologic exam may also be done.
Blood tests will be done to look for any hormone changes.
An ultrasound may be done to create images of the reproductive organs.
There is no known cure for Turner syndrome. However, there are treatments for many of the associated problems. These include:
If given early enough in childhood, growth hormone can improve growth and increase final adult height by a few inches. However, not all children have a good response to growth hormone.
Bone-lengthening surgery can increase the final height of children with Turner syndrome who have not responded well to growth hormone. This treatment requires multiple surgeries, long periods of disability, and many potential complications.
Estrogen replacement therapy creates the normal physical changes of adolescence, including breast growth and menstrual periods.
Women with Turner syndrome usually take estrogen-progesterone treatment until at least menopause to protect their bones from osteoporosis.
Other medical problems are carefully monitored and treated, including:
