Background: Increased risk of spontaneous pneumothorax has been described in patients with Marfan syndrome and has been attributed, in part, to the presence of apical blebs and bullae. Objectives: We assess the risk of pneumothorax and its relationship to the presence of apical blebs and bullae in patients with Marfan syndrome in the era of CT imaging. Methods: A retrospective cohort study was ...
OBJECTIVES Marfan syndrome is an autosomal dominant inherited disorder of connective tissue. The vascular complications of Marfan syndrome have the biggest impact on life expectancy. The aorta of Marfan patients reveals degradation of elastin layers caused by increased proteolytic activity of matrix metalloproteinases (MMPs). In this study we performed adenoviral gene transfer of human tissue i...

To examine the associations among fibrillin gene mutations, protein function, and Marfan syndrome phenotype, we screened for alterations in the fibrillin coding sequence in patients with a range of manifestations and clinical severity. A cysteine to serine substitution at codon 1409 (C1409S) was identified in an epidermal growth factor (EGF)-like motif from one fibrillin allele which segregates...
Marfan syndrome is a well-described autosomal dominant connective tissue disorder with a constellation of anatomic characteristics including aortic degeneration as a result of the spontaneous mutation of the fibrillin gene, FBN1. Whereas life-threatening dissection and ascending aneurysmal rupture have been thoroughly documented in the literature, aneurysms of the abdominal aorta and those pres...
TGFBR1 and TGFBR2 gene mutations have been associated with Marfan syndrome types 1 and 2, Loeys-Dietz syndrome and isolated familial thoracic aortic aneurysms or dissection. In order to investigate the molecular and clinical spectrum of TGFBR2 mutations we screened the gene in 457 probands suspected of being affected with Marfan syndrome or related disorders that had been referred to our labora...
Investigation of muscle bioenergetics in the Marfan syndrome indicates reduced metabolic efficiency.
BACKGROUND The Marfan syndrome is an inherited multisystem disorder caused by mutations in fibrillin 1, with cardiovascular involvement being the most important feature of the phenoptype. Affected individuals have impaired flow-mediated dilatation (FMD) of large arteries of a similar severity to patients with chronic heart failure (CHF). AIMS Skeletal muscle bioenergetics were studied in pati...
