Orphanet leds av ett europeiskt konsortium bestående av 38 länder med koordination från Frankrike.

Nationella team ansvarar för insamling av data om specialistkliniker, medicinska laboratorier, pågående forskning samt patientorganisationer i deras respektive land.
Det franska koordinerande teamet ansvarar för Orphanets infrastruktur, förvaltningsverktyg, kvalitetskontroll, diagnosförteckning, klassificering och produktion av encyklopedin.

Orphanet styrs av olika kommittéer, vilka oberoende övervakar projektet för att tillse dess samstämmighet, utveckling och hållbarhet.

På europeisk nivå:

Styrgruppen består av representanter från de myndigheter och organ som finansierar Orphanets infrastruktur och koordination. Ledningsgruppen består av de nationella koordinatorerna och dess ordförande är chefen för Inserm-Orphanet. Redaktionsrådet består av över 100 internationella experter.

På nationell nivå:

De 38 länderna som deltar i Orphanet har var sitt vetenskapliga råd som består av nationella experter från de flesta medicinska specialiteter med erfarenheter från arbete med ovanliga diagnoser. Rådsmedlemmarna konsulteras vid behov för att validera kvalitén av den insamlade informationen samt hjälpa till att identifiera experter inom respektive specialitet.


Infrastrukturen och koordinationen finansieras i huvudsak av Inserm (det franska nationella institutet för hälsa och medicinsk forskning), det franska direktoratet för hälsa samt av EU-kommissionen (20091215).

Orphanets nationella aktiviteter finansieras av institutioner i de deltagande medlemsländerna och/eller särskilda kontrakt. Karolinska Institutet har tagit på sig rollen som nationell samordnare för Orphanet i Sverige.

The website is governed by French law. Users outside of French territory must categorically accept the enforcement of French laws when visiting the website and using any of the website’s functions.

To the best of its ability, INSERM US14 aims to ensure the accuracy and the regular update of information at the moment of publication on the website.

However, INSERM US14 cannot wholly guarantee the accuracy, precision nor the exhaustively of the information available on the website. The information available on the website is non-contractual, and can be changed at any time.

Information provided by Orphanet is not intended to replace professional health care. Only medical professionals are authorised to give medical advice.

The information provided in Orphanet’s encyclopaedia is based on published scientific articles. Disease profiles are expert-authored and peer-reviewed texts. These general texts may not apply to specific cases, due to the extensive variability of disease expression. Some information may appear shocking. It is of the utmost importance to check if the provided information is relevant or not to a specific case.

Information in Orphanet is updated on a regular basis. It may happen that new discoveries are made in between updates and do not yet appear in the disease profile. The date of the last update is always indicated. Professionals are encouraged to always consult the most recent publications before making any decisions based on the information provided.

Orphanet cannot be held responsible for harmful, truncated or erroneous use of any information found in the Orphanet database.

Not all rare diseases are indexed by their clinical signs in Orphanet at the moment. As Orphanet only covers rare diseases, this function cannot be used to make a differential diagnosis with common diseases, which should be considered first when making a diagnosis. The clinician using the information provided in Orphanet is solely responsible for the diagnosis made.

The classifications are produced using scientific publications and/or expert opinion. The classifications are updated on a regular basis, and new classifications are added when available. Orphanet cannot guarantee the exhaustivity of these classifications.

Information concerning expert resources is collected on a national level in participating countries. The database cannot be considered to be exhaustive. If an expert centre, an expert laboratory, a professional, a research project, a clinical trial, a registry, a patient organisation or an institution is not listed for a certain region or country, this could be because Orphanet has not yet identified this information, or because the person in charge has refused to be listed in Orphanet or has not sent back the form they received to fill in. It is also possible that no expert centre, expert laboratory, professional, research project, clinical trial, registry, patient organisation or institution exists for the zone or the disease in question. Not all rare diseases have specialised resources at the present time.

In no circumstance should the listed expert centres be considered to be the only centres suitable for diagnosis and treatment. These centres are intended to provide an expert opinion when needed.
