title: The fragile X gene and its function.
abstract: The fragile X syndrome represents the most common inherited cause of mental retardation worldwide. It is caused by a stretch of CGG repeats within the fragile X gene, which increases in length as it is transmitted from generation to generation. Once the repeat exceeds a threshold length, no protein is produced resulting in the fragile X phenotype. Ten years after the discovery of the gene, much has been learned about the function of the fragile X protein. Knowledge has been collected about the mutation mechanism, although still not all players that allow the destabilization of the CGG repeat are known.
