Fragile X syndrome is a genetic condition caused by a mutation in the FMR1 gene on the X chromosome. It is the most common inherited form of intellectual disability and can affect both males and females, though males typically experience more severe symptoms. Individuals with this syndrome may have developmental delays, learning disabilities, and social challenges. Symptoms of Fragile X syndrome can also include behavioral issues such as anxiety and attention problems. Physical features may include a long face, large ears, and flexible joints. Early diagnosis and intervention can help manage symptoms and improve quality of life for those affected.
