 Marfan syndrome (MFS) is an autosomal dominant condition with a reported incidence of 1 in 3000 to 5000 individuals and is one of the most common inherited disorders of connective tissue. While most MFS patients have an affected parent, around 15 – 30 percent have a de novo mutation. MFS is associated with a broad range of clinical symptoms and associated disorders, ranging from classic ocular, cardiovascular, and musculoskeletal abnormalities to manifestations including involvement of the lung, skin, and central nervous system.
-Progressive dilatation of the ascending aorta is one of the key features, which causes a high risk of sudden death due to aortic dissection or rupture in young Marfan patients. (figure 18 and 19)

 The underlying genetic defect is localised in the fibrillin gene on chromosome 15 (FBN1) in which recently around 600 different mutations are found. However in about 10% of MFS patients there is no mutation identified in the FBN1 gene, furthermore FBN1 mutations also occur across a wide range of milder phenotypes that overlap the classic Marfan phenotype. Therefore it is not possible to diagnose MFS solely with genetic information.
