RATIONALE Mutations in several genes have been identified that are responsible for 25% of families with familial thoracic aortic aneurysms and dissections. However, the causative gene remains unknown in 75% of families. OBJECTIVES To identify the causative mutation in families with autosomal dominant inheritance of thoracic aortic aneurysms and dissections. METHODS AND RESULTS Exome sequenc...
در بیماری als نیز بیماران مبتلا دارای تجمعات پروتئینی در جسم سلولی و آکسونهای نورونهای حرکتی بافت عصبی خود می باشند که بطور عمده متشکل از آنزیم سوپراکسید دیسموتاز 1 (sod1) است. جهش در ژن sod1 در 20% از موارد familial als (fals) مشاهده می شود و به عنوان یک عامل مهم در ایجاد این بیماری شناخته می شود. مکانیزم بیماری زایی تجمعات sod1در بیماری fals اگر چه هنوز به طور کامل مشخص نیست اما تغییر در خصوص...
BACKGROUND Thoracic aortic aneurysm/dissection (TAAD) is a common phenotype that may occur as an isolated manifestation or within the constellation of a defined syndrome. In contrast to syndromic TAAD, the elucidation of the genetic basis of isolated TAAD has only recently started. To date, defects have been found in genes encoding extracellular matrix proteins (fibrillin-1, FBN1; collagen type...
BACKGROUND The natural history of thoracic aortic aneurysm is incompletely understood. Over the last 10 years, at Yale University we have maintained a large computerized database of patients with thoracic aortic aneurysms and dissections. Analysis of this database has permitted insight into fundamental issues of natural behavior of the aorta and development of criteria for surgical intervention...
Total variation was recently introduced in many different magnetic resonance imaging applications. The assumption of total variation is that images consist of areas, which are piecewise constant. However, in many practical magnetic resonance imaging situations, this assumption is not valid due to the inhomogeneities of the exciting B1 field and the receive coils. This work introduces the new co...
Mutations in the gene encoding transforming growth factor-beta receptor type II (TGFBR2) have been described in patients with Loeys-Dietz syndrome (LDS), Marfan syndrome type 2 (MFS2) and familial thoracic aortic aneurysms and dissections (TAAD). Here, we present a comprehensive and quantitative analysis of TGFBR2 expression, turnover and TGF-β-induced Smad and ERK signaling activity for nine m...
Thoracic aortic aneurysm/dissection (TAAD) is a potential lethal condition with a rising incidence. This condition may occur sporadically; nevertheless, it displays familial clustering in >20% of the cases. Family history confers a six- to twentyfold increased risk of TAAD and has to be considered in the identification and evaluation of patients needing an adequate clinical follow-up. Familial ...
Genetic studies over the past several decades have helped to better elucidate the genomics and inheritance of thoracic aortic diseases. Seminal work from various researchers have identified several genetic factors and mutations that predispose to aortic aneurysms, which will aid in better screening and early intervention, resulting in better clinical outcomes. Syndromic aneurysms have been asso...
