Current Research

Scientists are conducting research on Marfan syndrome to better understand what happens once the genetic defect or mutation occurs and How it changes the way connective tissue develops and functions in the body.

other scientists are evaluating the usefulness of certain medications in preventing or reducing problems with the aorta.

the research helps to pinpoint more effective treatments for Marfan syndrome and the related disorders and to allow better diagnoses for Marfan syndrome.

the research "has helped reduce life-threatening problems from these conditions, identified treatments that have improved the quality of life, and helped people to live a long life with Marfan syndrome and related disorders."
