Fragile X syndrome, also known as Martin-Bell syndrome or FXS, is the most common known cause of inherited intellectual disability, occurring in an estimated 1 in 4000 males and 1 in 6000 to 8000 females.
Many support groups for Fragile X exist, sometimes overlapping with autism support groups as concerned individuals come together to help those with ASD, FXS, or both.
Other genetic factors may account for the reason that some children with FXS have autism as well, but further study is underway to determine the factors.
FXS is caused by a mutation in a gene on the X chromosome that interferes with the production of a protein needed for proper brain development.
Like autism, the most help for children with FXS is simply the concern, love, and dedication of the adults who care for them.
FXS is an inherited genetic disorder, the mutated X passed from one generation to another in affected families.
People with Fragile X Syndrome, or FXS, may also have autism, and many people with autism also have FXS.
