Fragile X syndrome (FXS) is the most common cause of inherited intellectual disability and the most common known genetic cause of autism or autism spectrum disorders. Symptoms of FXS include a range from learning disabilities to more severe cognitive or intellectual disabilities. Delays in speech and language development are common, as are a variety of physical and behavioral characteristics. FXS is caused by a “full mutation” of the FMR1 Gene.
