Defects in the smooth muscle myosin heavy chain protein, encoded by MYH11 have been associated with FTAA and ascending TAA in association with patent ductus arteriosus. It is shaped like a cane with an arch at the top and runs from . Clinical . Though aortic aneurysms do not directly cause death, complications arising from an aneurysm - such as dissection or rupture - cause approximately 15,000 deaths annually. Groups review current disease and/or phenotype assertions (e.g. These aortic abnormalities are potentially life-threatening because they can decrease blood flow to other parts of the body such as the brain or other vital organs, or cause the aorta to break open (rupture).\n\nFamilial thoracic aortic aneurysm and dissection (familial TAAD) involves problems with the aorta, which is the large blood vessel . While majority of the cases are sporadic, more than 20% are inherited as a single gene disorder. Dissection refers to the actual tearing . There is also at least one additional major familial aortic aneurysm predisposition locus that remains to be identified.

Familial thoracic aortic aneurysm and aortic dissection (Familial TAAD) is a rare condition that affects the aorta (the large blood vessel that distributes blood from the heart to the rest of the body). Indications for surgical or endovascular repair are based on aneurysm location and risk factors for rupture such as aneurysm size, rate of growth, and associated conditions, while medical management is also . The most common familial TAA is Marfan syndrome (MFS), which is primarily caused by mutations in fibrillin-1 (FBN1) gene. Thoracic aortic aneurysm and dissection (TAAD) is a life-threatening disease affecting the aorta and is the 15th leading cause of death in the United States (Hoyert et al. Familial TAAD affects the upper part of the aorta, near the heart. A thoracic aortic aneurysm can progressively enlarge over time and doesn't usually have symptoms. Heritable thoracic aortic disease (HTAD) refers to thoracic aortic disease caused by mutation of a gene that confers a high risk for TAAD (see Causes ). A diagnosis of familial thoracic aortic aneurysm and dissection is made when there is a positive family history of aneurysm and dissection. Familial Aortic Aneurysm. FAD is thought to be passed down as an autosomal dominant disease and once inherited will result in dissection of the aorta, and dissecting aneurysm of the aorta, or rarely aortic or arterial dilation at a young age.
