Fragile X mental retardation 1 is the gene underlying fragile X syndrome (FXS). Its product, fragile X mental retardation protein, is closely involved with development of brain and neurons. PCR and Southern blotting have been the major methods for laboratory diagnosis of FXS. In this article, the progress in the molecular diagnosis of FXS is reviewed.
