Ehlers-Danlos syndrome is a group of inherited disorders marked by extremely loose joints, hyperelastic skin that bruises easily, and easily damaged blood vessels.

There are six major types and at least five minor types of Ehlers-Danlos syndrome (EDS).

A variety of gene mutations (changes) cause problems with collagen, the material that provides strength and structure to skin, bone, blood vessels, and internal organs.

The abnormal collagen leads to the symptoms associated with EDS. In some forms of the condition this can include rupture of internal organs or abnormal heart valves.

Family history is a risk factor in some cases.
