Rare Diseases and the PSOD Rare Disease Registry
What is a rare disease?
Rare diseases refer to “life-threatening or chronically debilitating diseases which are of such low prevalence that special combined efforts are needed to address them”.
- 10% to 15% of individuals worldwide are roughly estimated to be affected by rare disease, but the definition and categorization of rare diseases differ slightly by region.
- Definition of rare disease in some countries:
US = 1 in 1,500
Europe = 1 in 2,000
Japan = 1 in 4,000
Taiwan = 1 in 10,000 - 80% of rare diseases have identified genetic origins
- 50% of rare diseases affect children, and 30% of patients with rare diseases die before the age of 5
- 5,000-8,000 rare diseases are thought to exist2, with approximately 250 new diseases being described on an annual basis
