Several of the studies carried out in the CENUM laboratories require the active participation of affected individuals and their families. Some studies require limited participation (for example, only one visit) while others may require several meetings. To find out more about on-going studies and determine if you are eligible for participation, please contact the researchers working on the topics that are of interest to you.
