Turner syndrome is a genetic condition that affects girls and women. It occurs when one of the two X chromosomes that females typically have is either missing or partially missing. This happens in about 1 in every 2,000 to 2,500 girls born.
Turner syndrome is not inherited from parents and is not caused by anything the parents did or didn't do during pregnancy. It happens randomly when the egg or sperm is forming, or very early in pregnancy.
Common Features
Girls and women with Turner syndrome can have a wide range of features, and not everyone will have all of them. The most common characteristics include:
Growth and Development
Short stature (being shorter than average), which usually becomes noticeable around the age of 5
Delayed or absent puberty without treatment
Difficulty getting pregnant naturally, though some women with Turner syndrome can have children
Physical Features
Extra folds of skin on the neck (webbed neck)
Low hairline at the back of the neck
Swelling of the hands and feet, especially in newborns
Broad chest with widely spaced nipples
Medical Conditions
Heart problems, including narrowing of the aorta or abnormal heart valves (present in about one-third to one-half of individuals)
Kidney differences
Hearing problems
Thyroid conditions
Higher risk of diabetes and high blood pressure
Bone health concerns, including osteoporosis
Learning and Development
Most girls and women with Turner syndrome have normal intelligence. Some may experience challenges with math, spatial skills, or social situations, but these vary greatly from person to person.
If learning challenges are present, educational support and accommodations can be very helpful. Neuropsychological testing can identify specific areas where support may be beneficial.
Treatment and Management
With proper medical care, girls and women with Turner syndrome can lead healthy, fulfilling lives. Treatment is tailored to each individual's needs and may include:
Growth Hormone Therapy
Starting in early childhood, growth hormone injections can help increase height. This treatment can add about 3 to 4 inches to final adult height when started early.
Hormone Replacement Therapy
Most girls with Turner syndrome need estrogen therapy, usually starting around the age of 11 or 12 (the typical age for puberty). This helps to:
Develop breasts and other female characteristics
Start menstrual periods
Protect bone health
Support overall health and well-being
Hormone therapy usually continues throughout adulthood until around age 50.
Regular Medical Monitoring
As Turner syndrome can affect multiple body systems, regular check-ups are important. These may include:
Heart evaluations, including imaging tests
Blood pressure monitoring
Hearing and vision tests
Thyroid function tests
Bone density scans
Kidney function tests
Screening for diabetes
Living with Turner Syndrome
With advances in medical care and multi-disciplinary approach, girls and women with Turner syndrome are living longer, healthier lives than ever before. Many women with Turner syndrome:
Complete their education and pursue successful careers
Develop meaningful relationships
Participate fully in sports and activities
Lead independent, fulfilling lives
Fertility Options
While most women with Turner syndrome cannot get pregnant naturally, some options may be available, including egg donation and in vitro fertilization. It's important to discuss these options with a fertility specialist and cardiologist, as pregnancy can carry additional risks for women with Turner syndrome.
Getting Support
Managing Turner syndrome works best with a multi-disciplinary team which may include:
Endocrinologists (hormone specialists)
Cardiologists (heart specialists)
Geneticists
Reproductive specialists
Psychologists or counsellors
Primary care physicians
Support groups and organisations dedicated to Turner syndrome can also provide valuable resources, information, and connections with others who understand the condition.
When to Seek Care
If you notice any of the following in your daughter, talk to your healthcare provider:
Slower growth than expected
No signs of puberty by age 13
Swelling of hands or feet
Heart-related symptoms
Hearing or vision problems
Early diagnosis and treatment can make a significant difference in outcomes and quality of life.
