National Rare Diseases Office

What is a rare disease?
A ‘rare disease’ is defined in Europe as a life-threatening or chronically debilitating disease affecting no more than 5 people per 10,000. There are an estimated 6-8,000 known rare diseases affecting up to 6% of the total EU population, (at least 30 million Europeans), and perhaps up to 300,000 Irish people during their lives. This means that 6-8% of the Irish population or 1 person in 12 may have a rare disease at some stage in their lifetime. Approximately 70-80% of rare diseases are genetic and are present throughout the person’s entire life.

Learn more about rare diseases with the Irish Easy Guide to Rare Diseases 2013 which gives you more information and real-people stories.
