The Marfan Europe Network is a coalition of support organisations concerned with people affected by Marfan syndrome or related disorders. It was originally named European Marfan Support Network (EMSN) and was founded in 1991.

Marfan organisations within Europe form a network to support and encourage each other by exchanging and sharing information and working for the benefit of people with Marfan syndrome (or related disorders) and their families.

The meetings include lectures, discussions and exchange of experience. A youth group gives young people the possibilities to exchange their personal experiences.
