About Orphan Diseases
What is a rare or orphan disease?
A rare disease is a disease that affects a small number of people (less than 1 out of 2 000 official threshold in Europe i.e less than 30 000 in France for a given disease).

It is called "orphan" when there are no existing therapeutic solutions.

7 000 diseases are identified affecting 6 to 8 % of the world population.

Those diseases are serious, chronic, evolving and the vital prognostic is often at stake.
They remain unknown of physicians and health professionals and very often have no cure.
