How many people are affected or at risk of Turner syndrome?

Turner syndrome affects about 1 of every 2,500 female live births worldwide.1

This disorder affects all races and regions of the world equally. There are no known environmental risks for Turner syndrome. Parents who have had many unaffected children can still have a child with Turner syndrome later on.

Generally, Turner syndrome is not passed on from mother to child. In most cases, women with Turner syndrome are infertile.
