Fragile X syndrome is caused by a mutation or change in the FMR1 gene on the X chromosome. This gene provides instructions for making a protein called fragile X mental retardation protein (FMRP) which is needed for brain development. The mutation leads to a deficiency in FMRP resulting in fragile X syndrome, which is characterized by cognitive and developmental impairments.
