Rett Syndrome Program

The Greenwood Genetic Center has a longstanding interest and expertise in Rett syndrome, a rare, genetic neurodevelopmental disorder that affects mainly females. GGC’s Rett syndrome program includes clinical care, diagnostic testing, research projects, and clinical trials.

GGC has been named a Rett Syndrome Center of Excellence by the International Rett Syndrome Foundation (IRSF). We were proud to be a clinical trial site for DAYBUE, the first and only FDA-approved drug for Rett syndrome.

GGC works closely with IRSF to provide support and advocacy for those impacted by Rett Syndrome. Each year, GGC and IRSF work with the SC governor’s office to proclaim October as Rett Syndrome Awareness Month in SC.
