Which feature is a common physical characteristic of Fragile X Syndrome?

Fragile X Syndrome is known for several distinctive physical features, with large ears being one of the most common characteristics. Individuals with this genetic condition often present with an elongated face and prominent features, including large ears. The prominence of the ears can be attributed to the overall facial structure changes that occur in individuals with Fragile X Syndrome, which stem from the underlying genetic mutation on the X chromosome.

Other features associated with Fragile X Syndrome may include a high arched palate, macroorchidism in males, and sometimes behavioral issues, but the large ears are particularly recognized in clinical evaluations. This physical attribute is often one of the first things clinicians observe when assessing a patient for potential Fragile X Syndrome, making it a noteworthy characteristic.

In the context of the other options: a protruding tongue, short stature, and small hands are not widely recognized as primary features of Fragile X Syndrome, which is why they do not align with the common physical characteristics associated with this condition.
