Fragile X syndrome is the most common form of inherited mental retardation. A problem with a specific gene causes the disease. Normally, the gene makes a protein you need for brain development. But the mutation causes a person to make little or none of the protein, which results in the symptoms of Fragile X.
People with only a small change in the gene might not show any signs of Fragile X. People with bigger changes can have severe symptoms. These might include
- Intelligence problems, ranging from learning disabilities to severe mental retardation
- Social and emotional problems, such as aggression in boys or shyness in girls
- Speech and language problems, especially in boys
Fragile X has no cure. You can treat some symptoms with educational, behavioral or physical therapy, and with medicines. Getting treatment early for Fragile X can help.
