Fragile X Syndrome Support Group

Fragile X Syndrome is the most common inherited cause of mental retardation, and is associated with autism. The fragile X syndrome is a genetic disorder caused by mutation of the FMR1 gene on the X chromosome. Mutation at that site is found in 1 out of about every 4000 males and 1 out of about every 6000 females.
