Family Nurse Practitioner Exam

What additional feature can be seen in individuals with Fragile X disorder apart from the intellectual disabilities?

1. Hyperactivity

2. Facial hair growth

3. Joint hyperlaxity

4. Severe visual impairments

The correct answer is: Joint hyperlaxity

Individuals with Fragile X syndrome often exhibit a range of physical and behavioral features in addition to intellectual disabilities. Joint hyperlaxity, which is characterized by an increased range of motion in the joints, is one of the common physical manifestations observed in those with the disorder. This flexibility can sometimes lead to joint issues or discomfort but is a recognized clinical feature associated with Fragile X syndrome. In contrast, while hyperactivity may be observed in some individuals with Fragile X, it is not as prominent or distinctive as joint hyperlaxity. Similarly, facial hair growth is not typically associated with Fragile X but may occur independently of the disorder. Severe visual impairments do not generally characterize Fragile X syndrome, as the primary issues are cognitive and behavioral. Understanding these attributes enhances the recognition of Fragile X features beyond intellectual impairment, highlighting the importance of recognizing the complete clinical picture for effective management and support.
