ERNs

What are the European Reference Networks?

“European Reference Networks: Connecting Expertise for Better Care for People Living with Rare Diseases”

You have probably heard of rare diseases and complex conditions (in the EU alone, between 27 and 36 million people live with a rare disease), but you may not yet be familiar with the ERNs, or European Reference Networks. From JARDIN we want to highlight their value and give visibility to their undertakings.

European Reference Networks (ERNs) are multinational networks of highly specialised healthcare providers (HCP) across Europe in thematically coherent medical domains, addressing rare or low-prevalence complex diseases or conditions requiring exceptional concentration of expertise and resources.

JARDIN aims to enhance the impact of the ERNs even further by addressing all aspects of their better integration into national healthcare systems in MS, Norway, and Ukraine.


There are currently 24 ERNs providing virtual expert consultations for people living with rare diseases or complex conditions from all member states (MS), Norway, and Ukraine, as well as support knowledge generation, professional training and education, and research.

Here is the complete list of the European Reference Networks, so you can easily find out the health scope of each one and visit their websites to learn more about them.
