Name
Familial thoracic aortic aneurysm and dissection (TAAD);
Aortic aneurysm familial thoracic type (AAT)
Description
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.
