What symptom is NOT typically associated with Turner's Syndrome?

In the context of Turner's Syndrome, the symptoms commonly observed include short stature, webbed neck, and various cardiac anomalies, such as heart defects. Each of these manifestations can be traced back to the genetic abnormalities associated with the syndrome, which arises from the complete or partial absence of one of the two X chromosomes in females.

Developmental delays are not a typical characteristic associated with Turner's Syndrome. While individuals with this condition may experience some challenges, particularly in areas related to spatial reasoning or mathematics, they often do not exhibit significant developmental delays as seen in other genetic syndromes. Instead, cognitive development is generally within the average range for many affected individuals, allowing them to succeed academically and socially.

Thus, the lack of a direct link between Turner's Syndrome and significant developmental delays makes this symptom the correct choice when identifying which one is not usually associated with the condition.
