GGC Fragile X Syndrome Program

What is Fragile X Syndrome?

Fragile X syndrome (FXS) is a genetic condition that causes intellectual disability, behavioral and learning challenges and various physical characteristics. Though FXS occurs in both genders, males are more frequently affected than females, and generally with greater severity - National Fragile X Foundation

The Greenwood Genetic Center is part of the National Fragile X Clinical and Research Consortium, which is funded by the National Fragile X Foundation and the US Centers for Disease Control and Prevention.

Clinical Care

  • The Greenwood Genetic Center's Fragile X syndrome (FXS) clinics serve both pediatric and adult patients with FXS.
  • FXS clinics involve a clinical geneticist, genetic counselor, a developmental behavioral pediatrician and a neurologist.
  • GGC's FXS clinic can also assist with referrals to local medical specialists and behavioral and therapy services. Genetic testing is also available through GGC's Molecular Diagnostic Laboratory.
  • The Center's Greenville, SC office is the clinical home for the FXS clinic. Travel reimbursement to Greenville is available through the NFXF and the Fly with Me Fund. Clinic visits and research study enrollment in FORWARD can also be perfomed at other GGC locations and may include telemedicine and telegenetics.


  • FORWARD: In collaboration with Emory University School of Medicine, GGC is a site of FORWARD (Fragile X Online Registry With Accessible Research Database), a multisite observational natural history study affiliated with the FXCRC. FORWARD acts as a research hub to connect patients to current projects.
  • Clinical Trials: GGC is involved in the oversight of the NeuroNEXT clincial trial NN107, the Effects of AFQ056 on Language and Learning in Young Children with Fragile X Syndrome (FXS), funded by the National Institiute of Neurological Disorders and Stoke (NINDS) of the National Institiutes of Health.
  • ASD in FXS: Research efforts of Dr. Kaufmann and the FXCRC have focused on the codiagnosis of autism spectrum disorder (ASD) and FXS. A publication in Pediatrics explores the impact of ASD codiagnosis in FXS in terms of neurologic and behavioral co-occurring conditions and treatment approaches.
