What physical feature is commonly associated with Turner's syndrome?

Turner's syndrome, a chromosomal disorder typically characterized by the absence of all or part of one of the X chromosomes in females, presents with several distinctive physical features. One of the most commonly recognized features is the presence of a webbed neck, which results from the abnormal lymphatic development that can occur in this condition. This webbing is often due to the accumulation of lymphatic fluid in the posterior neck region, contributing to the characteristic appearance of individuals with Turner's syndrome.

The other features that could be considered for this condition, such as small hands and feet, clubfoot, and long limbs, are less specific or more variable among patients. Individuals with Turner's syndrome may also have short stature and a variety of skeletal anomalies, but the webbed neck is particularly distinct and consistently noted in clinical observations, making it a common physical sign associated with the syndrome.
