What causes Ehlers-Danlos syndrome?

Ehlers-Danlos syndrome can be caused by changes (mutations) in several different genes (COL5A1, COL5A2, COL1A1, COL3A1, TNXB, PLOD1, COL1A2, and ADAMTS2). However, the underlying genetic cause is unknown in some families.[1]

Mutations in these genes usually alter the structure, production, and/or processing of collagen or proteins that interact with collagen. Collagen provides structure and strength to connective tissues throughout the body. A defect in collagen can weaken connective tissues in the skin, bones, blood vessels, and organs resulting in the features of the disorder.[2]
