Which syndrome is associated with edema, short stature, and a webbed neck?

Turner syndrome is characterized by several distinct physical features, one of which is a webbed neck. This condition occurs in females who typically have a complete or partial absence of one of the X chromosomes (45,X). Alongside a webbed neck, individuals with Turner syndrome often present with symptoms such as short stature and edema, particularly noticeable in infancy or early childhood.

The presence of edema is especially common in newborns, where it can manifest as swelling in the hands and feet. Individuals with Turner syndrome may also experience cardiovascular issues and renal anomalies, but the classic trio of symptoms—short stature, webbed neck, and edema—contributes to the distinctive clinical picture that leads to the diagnosis.

In contrast, other syndromes listed have different characteristic features. For instance, Down syndrome is associated with developmental delays and certain facial features such as a flat facial profile and slanted eyes, while Klinefelter syndrome mainly affects males and is characterized by the presence of an extra X chromosome, leading to symptoms like reduced testosterone and gynecomastia. Williams syndrome is known for cardiovascular issues and unique facial features but does not generally present with a webbed neck or edema.

Thus, the correct identification of Turner syndrome is supported by its specific manifestations, particularly
