Which of the following is a common symptom associated with Turner Syndrome?

1. Tall stature

2. Short stature

3. Increased muscle mass

4. Enhanced cognitive abilities

The correct answer is: Short stature

Individuals with Turner Syndrome typically exhibit short stature as a common symptom. This condition arises due to the absence or structural abnormalities of one of the X chromosomes in females, impacting growth and development. Most girls with Turner Syndrome do not reach typical height compared to their peers, and this characteristic is often recognized in childhood. In addition to short stature, individuals with Turner Syndrome may also experience other physical features such as a variety of other developmental symptoms, but the defining characteristic often noted in clinical settings is the reduced height. The other options, such as tall stature, increased muscle mass, and enhanced cognitive abilities, are not typically associated with Turner Syndrome; hence, they do not accurately reflect the common symptoms of the condition.
