In the EU, a rare disease is one that affects no more than 1 person in 2,000. This means that between 6,000 and 8,000 different rare diseases affect or will affect an estimated 30 million people in the EU.

The area of rare diseases has been long recognised as a field where EU and international collaboration is an indispensable condition to progress.

RITA brings together leading European centres with expertise in diagnosis and treatment of rare immunological disorders. These rather potentially life-threatening conditions require multidisciplinary care using complex diagnostic evaluation and highly specialized therapies for all four themes: Primary immunodeficiency (PID), Autoinflammatory disorders (AID), Autoimmune disease (AI) and Pediatric Rheumatology (PR)
