Turner syndrome is a sex chromosomal condition in women that has an incidence rate of 1 in 2000 to 5000 live female births. (1) Girls and women who have it either have an absent X chromosome or there is an abnormality in one of the two X chromosomes. 

The exact cause for why the second X chromosome is missing or partially missing from cells is unknown. It is believed to result in a random cell division error while the reproductive cells of the parent are being formed. (2)

Girls and women with Turner syndrome may be born with typical female genitalia or the genitalia can appear slightly abnormal. Some girls are diagnosed at birth because of these abnormalities, while others have no noticeable symptoms and are not diagnosed until later when they fail to begin puberty or menstruate. In most cases, the cause of Turner syndrome is unknown, although in some cases it does run in the family.
