This tutorial walks you through everything you need to know about turner syndrome. We explain it in plain language, step by step, so whether you are a student, a patient, or simply curious, you will come away with a solid understanding.
We cover what it is, why it matters, how it is diagnosed, and what you can do about it. Key facts are called out along the way.
What is Turner syndrome? Turner syndrome is a genetic disorder that affects a girl’s development and appearance. It can also cause health problems such as infertility and heart problems.
What causes Turner syndrome? Turner syndrome happens because of a problem with a chromosome. Chromosomes are tiny “packages” in your cells that contain your genes. Genes carry information, called DNA, that controls what you look like and how your body works. Normally, girls receive one X chromosome from each parent. Turner syndrome happens when one of the X chromosomes is partially or completely missing.
What are the symptoms of Turner syndrome? Turner syndrome can cause many different symptoms. The symptoms may be mild for some people. But for others, Turner syndrome can cause serious health problems.
Some of the symptoms of Turner syndrome affect a person’s appearance. Most people with Turner syndrome are shorter than average. They may also have physical features such as:
A neck that is short and has extra skin (a “webbed” neck)
A low hairline in the back
Low-set ears
Swollen hands and feet
People with Turner syndrome may be born with heart and kidney defects. They usually don’t have typical sexual development and are infertile. They are also at risk for other health problems such as high blood pressure, type 2 diabetes, osteoporosis, and thyroid problems.
How is Turner syndrome diagnosed? Health care providers diagnose Turner syndrome based on symptoms and a genetic blood test called a karyotype test. Sometimes it is found in prenatal testing.
What are the treatments for Turner syndrome? There is no cure for Turner syndrome, but there are treatments for some of the symptoms:
If they are started in early childhood, hormone injections can often increase adult height by a few inches
Estrogen replacement therapy (ERT) can help start sexual development. It also protects against bone loss
Assisted reproduction technologies can help some women with Turner syndrome get pregnant
People who have Turner syndrome need regular health checks. It’s also important for them to have a care team that includes specialists who can treat the health problems caused by Turner syndrome.
