Marfan Syndrome is a genetic disorder of connective tissue caused by mutations in the FBN1 gene resulting in skeletal, ocular, and cardiovascular abnormalities. It is characterized by disproportionately long limbs, joint hypermobility, eye problems like ectopia lentis, and life-threatening issues like aortic aneurysm. Diagnosis is based on clinical assessment using systemic criteria. Management focuses on surveillance and prevention of complications through beta-blockers, surgery, and potentially losartan which may help slow aortic root growth. Prognosis has improved with current treatments but cardiovascular events remain common.
