Article Abstract

Fragile X syndrome is an inherited disease with cognitive, behavioral, and neurologic manifestations, resulting from a single genetic mutation. A variety of treatments that target individual symptoms of fragile X syndrome are currently utilized with limited efficacy. Research in animal models has resulted in the development of potential novel pharmacologic treatments that target the underlying molecular defect in fragile X syndrome, rather than the resultant symptoms. This review describes recent advances in our understanding of the molecular basis of fragile X syndrome and summarizes the ongoing clinical research programs.
