The Marfan Europe Network (M.E.N) was created in 1991. Today it is a non-profit legal entity incorporated under Belgian law, whose by-laws are available via this link (https://www.ejustice.just.fgov.be/tsv_pdf/2024/05/13/24073313.pdf). Currently, we invite potential donors to support their relative national Marfan organisation helping them to possibly participate in the sponsoring of a M.E.N meeting when their country is the host.
