The signs and symptoms of Marfan syndrome vary greatly, even among members of the same family. Some people experience only mild effects, but others develop life-threatening complications. In most cases, the disease tends to worsen with age.

Marfan syndrome features may include:

  • Tall and slender build
  • Disproportionately long arms, legs, fingers and toes
  • 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.
