Mapping a Locus for Familial Thoracic Aortic Aneurysms and Dissections ( TAAD2 ) to 3p24–25

Mapping a locus for familial thoracic aortic aneurysms and dissections (TAAD2) to 3p24-25.

BACKGROUND Familial thoracic aortic aneurysms and dissections (TAAD) occur as part of known syndromes such as Marfan syndrome but can also be inherited in families in an autosomal dominant manner as an isolated condition. Previous studies have mapped genes causing nonsyndromic familial TAAD to 5q13-15 (TAAD1) and 11q23.2-q24 (FAA1). Further genetic heterogeneity for the condition was evident by...

Familial thoracic aortic aneurysms and dissections: genetic heterogeneity with a major locus mapping to 5q13-14.

BACKGROUND Aneurysms and dissections affecting the ascending aorta are associated primarily with degeneration of the aortic media, called medial necrosis. Families identified with dominant inheritance of thoracic aortic aneurysms and dissections (TAA/dissections) indicate that single gene mutations can cause medial necrosis in the absence of an associated syndrome. METHODS AND RESULTS Fifteen...

Familial thoracic aortic aneurysms and dissections.

Rupture of thoracic aortic aneurysms and/or dissections is not rare, occurring in approximately 0.6% of all medicolegal autopsies. Most forensic pathologists are aware of the association between thoracic aortic aneurysms/dissections and trauma, atherosclerosis, inflammation and Marfan syndrome. In this report, we discuss a familial form of thoracic aortic dilatation and/or dissection that is di...

Familial thoracic aortic aneurysms and dissections: identification of a novel locus for stable aneurysms with a low risk for progression to aortic dissection.

BACKGROUND Thoracic aortic aneurysms leading to acute aortic dissections are the major diseases that affect the thoracic aorta. Approximately 20% of patients with thoracic aortic aneurysms and dissections (TAAD) have a family history of TAAD, and these patients present younger with more rapidly enlarging aneurysms than patients without a family history of aortic disease. METHODS AND RESULTS A...
