French Foundation for rare diseases


Wearing a solidarity bib for the French Foundation for Rare Diseases is a unique opportunity to offer some hope to people concerned by a rare disease.

In Europe, a disease is considered to be rare if less than 1 person in 2000 is affected by the illness(Rare disease affects few people).

Unfortunately, rare diseases are numerous (7000 are known and a lot more of them probably exist).  The cause is universal. 3 million individuals suffer from rare diseases in France and half of them are children.

Having a rare disease, is a real daily struggle with many obstacles to overcome : uncertain diagnosis, lack of treatment, isolation, daily care ...

It is therefore urgent to accelerate research! This is the main goal we have set for theFrench Foundation for rare diseases, which since 2012 has funded more than 360 scientific research projects.
