Marfan syndrome is named after Antoine Marfan, [11] the French pediatrician who first described the condition in 1896 after noticing striking features in a five-year-old girl. [ 12 ] [ 77 ] The gene linked to the disease was first identified by Francesco Ramirez at the Mount Sinai Medical Center in New York City in 1991.
Heritable connective tissue diseases are rare, each disorder estimated at one to ten per 100,000, of which Marfan syndrome is the most common. It is carried by the FBN1 gene on chromosome 15, which encodes the connective protein fibrillin-1, [ 12 ] [ 13 ] inherited as a dominant trait.
Rheumatic fever (RF), Marfan's syndrome and the Ehlers–Danlos syndromes are other typical causes. [6] Mitral valve stenosis (MVS) can sometimes be a cause of mitral regurgitation (MR) in the sense that a stenotic valve (calcified and with restricted range of movement) allows backflow (regurgitation) if it is too stiff and misshapen to close ...
Coronary artery ectasia is commonly found in patients with diseases of the connective tissue and an increased inflammatory response such as Marfan syndrome and Kawasaki Disease. [6] It can also be found transiently in patients that have undergone stent placement resulting in the stretching of the vessels 1.
Joint hypermobility syndrome shares symptoms with other conditions such as Marfan syndrome, Ehlers-Danlos Syndrome, and osteogenesis imperfecta. Experts in connective tissue disorders formally agreed that severe forms of Hypermobility Syndrome and mild forms of Ehlers-Danlos Syndrome Hypermobility Type are the same disorder. [citation needed]
[6] [7] Other potential causes that affect the valve directly include Marfan syndrome, Ehlers–Danlos syndrome, ankylosing spondylitis, and systemic lupus erythematosus. In acute cases of aortic regurgitation, the main causes are infective endocarditis, aortic dissection or trauma. [1]
Those affected by arrhythmogenic cardiomyopathy may not have any symptoms at all despite having significant abnormalities in the structure of their hearts. [6] If symptoms do occur, the initial presentation is often due to abnormal heart rhythms (arrhythmias) which in arrhythmogenic cardiomyopathy may take the form of palpitations, or blackouts. [7]
Marfanoid–progeroid–lipodystrophy syndrome (MPL), also known as Marfan lipodystrophy syndrome (MFLS) or progeroid fibrillinopathy, is an extremely rare medical condition which manifests as a variety of symptoms including those usually associated with Marfan syndrome, an appearance resembling that seen in neonatal progeroid syndrome (NPS; also known as Wiedemann–Rautenstrauch syndrome ...
