What is Ehlers-Danlos Syndrome (EDS)?

Ehlers-Danlos syndrome (EDS) is a complex group of rare hereditary disorders involving connective tissues. Connective tissues support parts of the body. Examples of connective tissues are skin, tendons, ligaments, and cartilage. EDS usually results in over-flexible (hypermobile) joints, over-elastic (hyperelastic) skin, and fragile tissues. There are at least six different varieties of EDS. They are classified according to how they are inherited and which structures of the body they mostly involve.
