Turner Syndrome

Turner syndrome (also referred to as gonadal dysgenesis) is a rare genetic disorder that only affects females. Approximately one in 2,000-5,000 females in the general population are affected with Turner syndrome. This is a large percentage considering that about 99% of pregnancies with fetuses affected with Turner syndrome spontaneously abort, usually during the first trimester of pregnancy. It is also estimated that 10% of all spontaneously aborted fetuses result from Turner syndrome.
