Ehlers Danlos Syndrome (EDS) is a genetic connective tissue disorder caused by defects in collagen. There are several subtypes of EDS with varying symptoms. The hypermobility type causes loose joints and double-jointedness. The classical type affects the skin, causing easy bruising and scarring. The vascular type is the most severe and can lead to organ and vessel rupture. While EDS has no cure, physical therapy can help strengthen joints to prevent dislocation. Gene therapy may one day treat EDS by replacing or inactivating mutated genes.
