Ehlers-Danlos syndromes (EDS) are a group of inherited connective tissue disorders caused by abnormalities in the structure, production, and/or processing of collagen. The new classification, from 2017, includes 13 subtypes of EDS. Although other forms of the condition may exist, they are extremely rare and are not well-characterized. The signs and symptoms of EDS vary by type and range from mildly loose joints to life-threatening complications. Features shared by many types include joint hypermobility and soft, velvety skin that is highly elastic (stretchy) and bruises easily. Mutations in a variety of genes may lead to EDS; however, the underlying genetic cause in some families is unknown. Depending on the subtype, EDS may be inherited in an autosomal dominant or an autosomal recessive manner. There is no specific cure for EDS. The treatment and management is focused on preventing serious complications and relieving associated signs and symptoms.
