The Rare Epilepsy Network is comprised of MEMBERS and PARTNERS. It is overseen by a Coordinating Committee comprised of volunteers from the Member Network. It is administered by a Director.

REN MEMBERs directly represent a rare epilepsy constituency and are committed to research and the REN mission and goals. They include Patient Advocacy Groups (PAGs) defined broadly irrespective of legal status (501c3) and may also include support and Facebook groups. REN MEMBERS also include other epilepsy or broader non-profit organizations who share a commitment to research on the rare epilepsies and the REN mission/goals. Groups that are not US-based are welcome to participate, since diseases and research have no boundaries, although some REN activities may focus on the United States funding and policies.
