Vascular Ehlers-Danlos syndrome is an inherited connective tissue disorder that is caused by defects in a protein called collagen. It is generally considered the most severe form of Ehlers-Danlos syndrome (EDS). Common symptoms include thin, translucent skin; easy bruising; characteristic facial appearance; and fragile arteries, muscles and internal organs. Vascular EDS is usually caused by a change (mutation) in the COL3A1 gene. Rarely, it may be caused by a mutation in the COL1A1 gene. Inheritance is autosomal dominant. Treatment and management is focused on preventing serious complications and relieving signs and symptoms.
