Furthermore, stroke is a well-known complication of several heritable connective tissue disorders, including Marfan's syndrome (FBN1 mutations) and Ehlers-Danlos syndrome type IV (COL3A1 mutations), which predispose to cervical artery dissection, the most frequent cause of cerebral ischemia at young age.
Aortic dilatation/dissection (AD) can occur spontaneously or in association with genetic syndromes, such as Marfan syndrome (MFS; caused by FBN1 mutations), MFS type 2 and Loeys-Dietz syndrome (associated with TGFBR1/TGFBR2 mutations), and Ehlers-Danlos syndrome (EDS) vascular type (caused by COL3A1 mutations).
