What is (are) Turner syndrome ?
Turner syndrome is a chromosomal disorder that affects development in females. It is characterized by a person having one X chromosome in each cell (females without Turner syndrome have two X chromosomes in each cell). Signs and symptoms may include short stature; premature ovarian failure; a "webbed" neck; a low hairline at the back of the neck; and swelling (lymphedema) of the hands and feet. Some people with Turner syndrome have skeletal abnormalities, kidney problems, and/or a congenital heart defect. Most affected girls and women have normal intelligence, but some have developmental delays, learning disabilities, and/or behavior problems. Turner syndrome is typically not inherited, but it can be inherited in rare cases. Treatment may include growth hormone therapy for short stature and estrogen therapy to help stimulate sexual development. While most women with Turner syndrome are infertile, assisted reproductive techniques can help some women become pregnant.
