Marfan syndrome is a genetic disorder characterized by connective tissue damage. Defects are particularly pronounced in the cardiovascular system, skeletal system, and eyes.
The disease is autosomal dominant (passed down in families in every generation, equally affecting men and women), caused by a defect in the FBN1 gene, which encodes the glycoprotein fibrillin-1. Fibrillin-1 is necessary for the proper formation of connective tissue.
Symptoms of the Disease

- Tall stature with long, thin limbs
- Long fingers of hands and feet (arachnodactyly)
- Frequent cases of scoliosis, pelvic and chest bone deformities
- Myopia, astigmatism, lens subluxation
- Early onset of glaucoma
- Cardiovascular problems – fatigue, shortness of breath, ischemic heart disease, valve defects.
- An important symptom is aortic aneurysm, which in women with Marfan syndrome can lead to an emergency situation during pregnancy – aortic dissection (regular echocardiographic checks every 6 weeks during pregnancy are necessary)
- Risk of developing pneumothorax
- The connective tissue defect manifests as weakening of the membrane lining the spinal cord, causing chronic back pain and abdominal pain
Marfan Syndrome Treatment
Cardiology – monitoring the condition of the aorta. Patients with Marfan syndrome are prone to aortic dissection – an emergency condition that is life-threatening. Prevention includes treating arrhythmias, reducing heart rate, and lowering blood pressure.
Musculoskeletal system – physiotherapy, pain relievers, and muscle relaxants are prescribed.
Animal studies have shown the promise of losartan (an angiotensin II receptor antagonist), which slows the formation of aortic aneurysm.
