Which condition is characterized by a webbed neck?

Turner syndrome is characterized by a variety of physical features and anomalies, one of the most notable being a webbed neck. This condition occurs when one of the two X chromosomes is missing or partially missing in females. The webbed neck is a result of abnormal lymphatic development, which often manifests as excess skin between the neck and shoulders.

In addition to the webbed neck, individuals with Turner syndrome may present with short stature, delayed puberty, and various cardiac and renal anomalies. Recognizing these distinctive features is crucial for early diagnosis and management. The other conditions listed do not typically present with this specific physical characteristic, which further highlights the uniqueness of Turner syndrome.
