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 more than 6000 known rare diseases affecting up to 6% of the total EU population (at least 30 million Europeans).

This means that at any time approximately 300,000 living in Ireland have a rare disease.
