MICYRN is a Canadian non-profit organization established in 2011 to reduce barriers and duplication of effort in multi-jurisdictional pediatric research, particularly for rare diseases. Rare diseases affect over 2.7 million Canadians but each affects fewer than 2000 individuals. MICYRN works to improve diagnosis of rare diseases and develop new therapies through national research networks and collaborating in international research initiatives. MICYRN also supports patient registries and clinical trials infrastructure to study rare diseases and determine drug safety and effectiveness in children through its research informatics platform and partnerships with health organizations and industry.
