Fragile X syndrome is a recently identified genetic disorder considered to be the most common inherited form of mental retardation. Current research is revealing that this chromosomal anomaly is linked to a variety of other educationally relevant problems including learning disabilities, attention deficit disorders, speech and language deficits, autistic characteristics, and behavior disorders. A description of the unique inheritance pattern reveals why milder forms of the syndrome are now beginning to be identified and educational interventions applied. This review highlights the physical, intellectual, academic, behavioral, and communication characteristics associated with fragile X. With knowledge of fragile X syndrome, the educator can play a key role in recognizing the disorder and referring for both early diagnosis and genetic counseling.
