Clinical Comment

Marfan syndrome (MFS) is a systemic disease of the connective tissue with variously combined symptoms of the heart, circulation, muscles, skeleton, eyes and lungs. The age at which it first manifests is variable; the first symptoms can occur at any age. Cardiovascular involvement is characterised by (i) progressive dilatation of the aorta with increased risk of prognostic aortic dissection and aortic valve insufficiency; and (ii) mital insufficiency with arrhythmias, endocarditis and heart failure. Skeletal involvement (including regrowth, arachnodactyly, hyperextensible joints, scoliosis) is often the first sign of disease. Symptoms of eye involvement include axial myopia (with the risk of retinal detachment) and lens shift (ectopy or luxation). Other possible symptoms include skin (striae), a risk of pneumothorax and dura-ectasia. The "classic" MFS is caused by mutations in the FBN1 gene (approx. 95% mutation detection probability in patients who meet the clinical criteria for MFS). Important differential diagnoses are MASS syndrome, Shprintzen-Goldberg syndrome, mitral valve prolapse, Ehlers-Danlos syndrome and other diseases with aortic aneurysm, e.g. Loeys-Dietz syndromes.
