Fragile X Syndrome is thought to be the most common hereditary cause of which condition?

1. Autism Spectrum Disorder

2. Intellectual Disabilities

3. Emotional Disturbance

4. Learning Disabilities

The correct answer is: Intellectual Disabilities

Fragile X Syndrome is recognized as the most common hereditary cause of intellectual disabilities. This genetic condition results from the mutation of the FMR1 gene located on the X chromosome. Individuals with Fragile X Syndrome often exhibit a range of cognitive and developmental challenges, with intellectual disability being a significant aspect of the disorder. The connection between Fragile X Syndrome and intellectual disabilities is well documented in clinical studies, which show that affected individuals frequently demonstrate varying degrees of cognitive impairment. While it is important to note that some individuals with Fragile X may have normal intelligence, a substantial proportion experience intellectual disabilities that can impact learning, communication, and daily functioning. In contrast, the other options outlined pertain to different aspects of cognitive, emotional, and academic challenges. While there may be links between Fragile X Syndrome and conditions such as autism spectrum disorder or learning disabilities, the most direct and well-established association is with intellectual disabilities, making this the correct choice.
