Turner Syndrome
What is Turner syndrome?
Turner syndrome is a chromosomal disorder that affects development in girls. It is caused by a missing or incomplete X chromosome. The genes
affected are involved in growth and sexual development, which causes short stature and individuals with Turner syndrome may have premature ovarian
failure. Many affected girls do not undergo puberty unless they are treated with the hormone estrogen.
About 30 percent of Turner syndrome patients have webbed neck (extra folds of skin on the neck), a low hairline at the back of the neck, puffiness
or swelling (lymphedema) of the hands and feet, skeletal abnormalities, and/or kidney problems. Approximately 33%-50% of girls with Turner syndrome
are born with a heart defect, such as Aortic coarctation (a narrowing of part of the aorta) or abnormalities of the aortic valve. Other problems
associated with Turner syndrome can include obesity, diabetes and hypertension, and osteoporosis is common.
