What is : (So we know you are human.)
Please supply the correct answer.
Fragile X Syndrome (FXS) represents the most common inherited cause of intellectual disability and autism, affecting approximately 1 in 4,000 to 6,000 individuals in the general population. About two-thirds of individuals with FXS have a form of autism spectrum disorder. FXS affects the X chromosome, specifically on the FMR1 gene; therefore, more males are diagnosed with FXS than females. Diagnosis of FXS is made through a DNA (blood) test. Cincinnati Children’s Hospital Medical Center’s Fragile X Research and Treatment Center, led by Craig Erickson, MD, serves males and females of all ages affected by FXS.
Since there is no cure for FXS, treatment focuses on improving the quality of life for the patient and family, which includes management of symptoms. An interdisciplinary team at Cincinnati Children's has been developed to provide an individualized level of treatment for each patient. The Fragile X Research and Treatment Center provides educational materials, behavioral medication management, behavioral and cognitive assessment, and behavior therapy interventions. Referrals are additionally available within the Cincinnati Children’s medical center system to speech therapy, occupational therapy, and special education consultation, and genetic counseling.
Physical and behavioral characteristics vary based upon the individual. Not all persons with FX will have all characteristics.
In addition to the full mutation of FXS, there are two known Fragile X-associated disorders (FXD), each thought to be caused by a change in the FMR1 gene.
Fragile X-associated tremor/ataxia
Fragile X-associated tremor / ataxia syndrome (FXTAS) is a neurodegenerative disorder, with an onset of 50 years of age or older. More males than females are affected. When females are affected, the symptoms are typically less severe. Symptoms of FXTAS include: balance problems, tremors, memory loss, personality change, and cognitive decline.
Fragile X-associated Primary Ovarian Insufficiency
Fragile X-associated Primary Ovarian Insufficiency (FXPOI) is caused by a premutation in the FMR1 gene. FXPOI is characterized by ovarian dysfunction, which can lead to infertility and an early-onset menopause.
Through participation in clinical trials and studies working to understand the biology of FX, the Fragile X Research and Treatment Center supports ongoing efforts to the contribution of scientific research in order to provide better outcomes for patients and families affected by FX.
