    Ehlers-Danlos syndrome (EDS) is a group of genetic disorders caused by faulty collagen synthesis; it affects the connective tissues and leads to symptoms such as overly elastic skin, joint hypermobility, and fragile blood vessels. In 2017, 13 variants of EDS were classified, and 12 had distinct genetic characteristics.

    Ehlers-Danlos syndrome (EDS) is a group of genetic disorders characterized by faulty synthesis of collagen proteins. Collagen is a vital component of connective tissue, which protects and supports many tissues and organs, including the skin, blood vessels, joints, and lungs. Faulty collagen in EDS can lead to overly elastic skin, joint hypermobility, atrophic scarring (a type of scar that doesn’t heal properly), and fragile blood vessels. Over the years, different types of EDS have been categorized, and in 2017, an international guideline was released with 13 variant classifications, 12 of which have known unique genetic characteristics.[1] [2]
