February is Marfan Syndrome Awareness Month. Marfan syndrome is a genetic disorder that affects the body’s connective tissue, which holds all the body’s cells, organs and tissue together.

People with Marfan syndrome are born with it, but it may not present itself right away. Learning more about the signs and symptoms here can help with development and treatment.
