Abstract:
Marfan syndrome (MFS) is one of the most common inherited connective tissue disorders that severely affects the cardiovascular system. Mutations in the gene encoding fibrillin-1 (FBN1) have been shown to cause MFS as well as dominant ectopia lentis and neonatal Marfan syndrome. Fibrillin-1 is the major component of elastic fiber microfibrils in the extracellular matrix of connective tissue. Recent molecular studies have brought some light into understanding the pathogenesis of MFS, but the diagnostic problems still prevail, and targeted therapy of MFS must await better dissection of the role of fibrillin-1 in tissue phenotype using different experimental systems.

- Connective Tissue Disorders
Background:
- Marfan syndrome (MFS) is a prevalent inherited connective tissue disorder.
- It significantly affects the cardiovascular system.
- Mutations in the fibrillin-1 (FBN1) gene are linked to MFS, ectopia lentis, and neonatal MFS.
Purpose of the Study:
- To review the current understanding of Marfan syndrome pathogenesis.
- To highlight diagnostic challenges in MFS.
- To emphasize the need for further research into fibrillin-1's role.
Main Methods:
- Review of recent molecular studies on MFS.
- Analysis of fibrillin-1's function in connective tissue.
