Symptoms

The signs and symptoms of Marfan syndrome can vary greatly, even among members of the same family, because the disorder can affect so many different areas of the body. Some people experience only mild effects, but others develop life-threatening complications.

Marfan syndrome features may include:

• Tall and slender build
• Disproportionately long arms, legs and fingers
• A breastbone that protrudes outward or dips inward
• A high, arched palate and crowded teeth
• Heart murmurs
• Extreme nearsightedness
• An abnormally curved spine
• Flat feet

When to see a doctor

If you think that you or your child may have Marfan syndrome, talk to your doctor or pediatrician. If your doctor suspects a problem, you'll likely be referred to a specialist for further evaluation.
