Marfan syndrome is a genetic disorder that affects the body's connective tissue, which provides support to various structures, including the heart, blood vessels, bones, and joints. People with Marfan syndrome often have tall and slender bodies, long limbs, and flexible joints. The condition can also lead to serious health issues, particularly affecting the heart and blood vessels, such as aortic dilation or aortic dissection. Diagnosis of Marfan syndrome typically involves a physical examination and imaging tests to assess the heart and blood vessels. While there is no cure, early detection and regular monitoring can help manage symptoms and reduce the risk of complications. Treatment may include medications or surgery to address specific health concerns.
