Marfan syndrome (MFS) is a relatively rare disease of the connective tissue that affects several organs of the body. Cardiovascular abnormalities such as aortic root dilatation and mitral valve prolapse are the two main life-threatening complications associated with MFS. The complete pathogenesis of MFS is yet unclear. However, fibrillin-1 (FBN1) gene mutations and mutations in the transforming growth factor-β (TGFβ) signaling pathway are the leading causes of this lethal disease. Detailed assessment based on several major and minor clinical manifestations has led to the evolution of different nosologies for MFS diagnoses with reliable accuracies. Nevertheless, heterogeneous disease advancement and overlapping clinical outcomes make MFS diagnosis challenging. Rapid strides in research and surgical avenues over the last two decades have improved the life expectancy and the quality of life of MFS patients remarkably. More specific diagnostic criteria have been established, novel therapeutic targets for pharmacotherapy have been identified and validated, and newer surgical techniques have been tested. Current research efforts are focusing on the identification of prognostic biomarkers, gene modifiers, drug targets, and surgical procedures. This review aims to provide a brief overview of these aspects associated with MFS.
