Turner Syndrome is a condition in which a female is partly or completely missing an X chromosome.Often a short and webbed neck, low-set ears, low hairline at the back of the neck, short stature, and swollen hands and feet are seen at birth. Typically, they only develop menstrual periods and breasts with hormone treatment, and are unable to have children without reproductive technology. Heart defects, diabetes and low thyroid hormone occur more frequently.Vision and hearing problems may also occur more often. No cure for Turner syndrome is known. Treatment, however, may help with symptoms. Human growth hormone injections during childhood may increase adult height. Estrogen replacement therapy can promote development of the breasts and hips.
