Turner syndrome is a genetic disorderthat affects about 1 in every 2,000 baby girls and only affects females.
A girl with Turner syndrome only has one normal X sex chromosome, rather than the usual two (XX).
This chromosome variation happens randomly when the baby is conceived in the womb. It is not linked to the mother's age.
Almost all girls with Turner syndrome:
As height and sexual development are the two main characteristics, Turner syndrome may not be diagnosed until a girl fails to show sexual development associated with puberty, usually between the ages of8 and 14 years.
Other characteristics of Turner syndrome can vary significantly between individuals.
However, it is usually possible to lead a relatively normal and healthy life.
Life expectancy is slightly reduced, but it can be improved with regular health checks to identify and treat potential problems at an early stage.
This helps scientists look for better ways to prevent and treat this condition. You can opt out of the register at any time.
Turner syndrome is a genetic disorder that only affects females. It causes a wide range of symptoms and some distinctive characteristics.
The symptoms of Turner syndrome vary depending on the age of the girl or woman affected.
Turner syndrome is a genetic condition caused by a missing or incomplete sex chromosome.
Turner syndrome is sometimes diagnosed before a baby is born, although it is often identified during childhood or at puberty.
There is no cure for Turner syndrome, but many of the associated symptoms, such as short stature, sexual development problems and learning difficulties, can be treated.
