Turner's Syndrome

Turner's syndrome (also known as Ullrich–Turner syndrome, gonadal dysgenesis, and 45,X syndrome) is a chromosomal disorder that causes a child to be born with a short webbed neck, low-set ears, low hairline at the back of the neck, short stature, and swollen hands and feet. Those affected by this disorder are born externally female but have a damaged or non-existent X chromosome. They typically do not grow breast or menstruate and are subject to heart defects, diabetes, and low thyroid hormone. They also frequently experience vision and hearing problems with many having noted difficulty in spatial visualization.
