Turner syndrome
A genetic disorder affecting only females, in which the patient has one X chromosome in some or all cells; or has two X chromosomes but one is damaged. Signs include short stature, delayed growth of the skeleton, shortened fourth and fifth fingers, broad chest, and sometimes heart abnormalities. Women with Turner syndrome are usually infertile due to ovarian failure. Diagnosis is by blood test (karyotype). Treatment may include human growth hormone and estrogen replacement
