Causes of Fragile X Syndrome

Fragile X Syndrome is a genetic disorder on the FMR - 1 gene. It produces none or too little of the protein. This is caused when the gene CGG repeats over 200 times. Most people have 6 - 200 repeats and this causes the protein to be made. When the gene is repeated more than 200 times the gene shuts of and does not make protein.
