What Is Marfan Syndrome?

Marfan syndrome is a genetic condition that affects the body’s connective tissue. Connective tissue holds all parts of the body together and helps control how the body grows.

Because connective tissue is found throughout the body, Marfan syndrome can affect many different parts of the body, including the heart, blood vessels, bones, joints and eyes. Though people are born with this condition, the symptoms of Marfan syndrome may not appear for a while.
