Conditions We Treat: Marfan Syndrome

Marfan syndrome is a genetic disorder of the connective tissue — the cells that support or connect different structures in the body. People with Marfan syndrome may have long, thin arms and legs, chest wall abnormalities, a curved spine and lens dislocation or severe myopia (nearsightedness). Marfan syndrome's most dangerous features are enlargements of the aorta and defects of the heart's mitral valve.

Marfan Syndrome: What You Need to Know

  • In two thirds of cases the condition is inherited, but each person can have a different subset of possible symptoms.
  • Diagnosis may involve an echocardiogram, a slit-lamp eye exam, a skeletal examination, family history and genetic testing.
  • Because Marfan syndrome affects many different systems of the body, you should be treated by a team of health care professionals knowledgeable about the range of potential effects.
  • Goals of treatment are to reduce stress on the aorta, obtain good vision correction and reduce bone and muscle complications and pain. In some cases surgery may be necessary.

Although Marfan syndrome shares features with other connective-tissue disorders such as Loeys-Dietz, Shprintzen-Goldberg and Ehlers-Danlos syndromes, it stems from different genetic mutations. The conditions are also managed differently.

Our Research

Discovering Marfan syndrome's genetic cause — a flawed protein in connective tissue — should have convinced doctors to give up on finding a real treatment. But Johns Hopkins researchers kept digging and found a way to treat the flaw using a decades-old medication.
