EDS Types

There are six major types of EDS:

Ehlers-Danlos syndrome (EDS) is a group of inherited connective tissue disorders, caused by various defects in the synthesis of collagen. EDS is known to affect men and women of all racial and ethnic backgrounds.

There are six distinct types of EDS currently identified. All share joint laxity, soft skin, easy bruising, and some systemic manifestations. Each type is thought to involve a unique defect in connective tissue, although not all of the genes responsible for causing EDS have been found.

These six types are defined according to the signs and symptoms that are manifested, in a set of major and minor diagnostic criteria for each type. Each type of EDS is a distinct disorder that “runs true” in a family. This means that an individual with Vascular Type EDS will not normally have a child with Classical Type EDS. There a number of mutations identified as Ehlers-Danlos syndromes since the 1997 diagnostic criteria; these lie outside the classifications and can be located through the OMIM/Online Mendelian Inheritance in ManĀ® database from Johns Hopkins University.
