Thoracic aortic aneurysms leading to acute aortic dissections (TAAD) are the major diseases that affect the thoracic aorta. While majority of the cases are sporadic, more than 20% are inherited as a single gene disorder. Familial TAAD is diagnosed based on the presence of dilatation and/or dissection of the thoracic aorta, absence of clinical features of Marfan syndrome, Loeys-Dietz syndrome, or vascular Ehlers-Danlos syndrome, and presence of a positive family history of TAAD. TGFBR2, TGFBR1, MYH11, ACTA2, and two loci on other chromosomes, AAT1 and AAT2, are associated with familial TAAD.
