European Network and Registry
for Homocystinurias and Methylation Defects

E-HOD is an acronym for the “European network and registry for Homocystinurias and methylation Defects”. E-HOD started as an EU project (The E-HOD project; No.2012_12_02) and has received funding from the European Union in the framework of the Health Program for three years. From 2019, EHOD has been transformed into the legal structure of an international collaboration between more than 70 centers from all over the world interested in these rare diseases. Collaboration encompasses participation in the E-HOD registry, research activities and guideline development. 

The registry is the core activity of E-HOD. Here, our collaboration partners enter anonymized patient data and we have been able to collect data from more than 700 patients with one of these rare diseases. After entering baseline data, one follow-up visit per patient per year is documented. The registry helps us to learn more about the natural course of the disease, treatment options and patients’ outcome over the years. 

Research and guideline development are closely related to the registry activities and establishment of a scientific network for the homocystinurias and methylation disorders. E-HOD helps medical professionals to meet and discuss patients, to seek help when facing a problem and to develop research projects with the aim to improve patient care and outcome by better understanding the diseases and treatments. Guidelines ensure that state-of-the-art knowledge is transferred to any site seeing affected patients and thus facilitate equal treatment. The EHOD network also includes patient representatives. Together with them, EHOD has organized successful patient-expert meetings, included patient advice in guidelines and included patients’ and families’ perspectives in exploration of new aspects of patient care and research.

E-HOD is always open to new collaboration partners.

The present structure of the E-HOD consortium

The E-HOD collaboration constitutes of over 70 institutions worldwide. Partner institutions name a metabolic specialist who represents them as a member with full voting rights.

At the annual meeting of members, decisions about projects, future activities etc. are made and active collaboration between partners is facilitated and encouraged.

The Executive Board of E-HOD has been elected in September 2022 for a period of three years. Members to the Executive Board are Martina Huemer (Bregenz, Austria; Chairperson), Matthias Baumgartner (Zurich, Switzerland), Carlo Dionisi-Vici (Rome, Italy), Luciana Hannibal (Freiburg, Germany), Stefan Kölker (Heidelberg, Germany), Viktor Kozich (Prague, Czech Republic) and Andrew Morris (Manchester, UK). The scope of the Executive Board is to initiate research, foster collaboration, update guidelines, and provide financial means to sustain the registry and other project activities.

The Scientific Board (established in 2022, members elected for 3 years) critically revises projects submitted to EHOD, helps in developing and improving research projects and advises the Executive Board on all research-related issues. 

Present members to the Scientific Board: Ivo Baric (Zagreb, Croatia; co-chair) and Luciana Hannibal (Freiburg, Germany; co-chair), Matthias Baumgartner (Zurich, Switzerland), Giorgia Olivieri (Rome, Italy), Luciana Hannibal (Freiburg, Germany), Tawfeq Ben-Omran (Doha, Qatar), Can Ficicioglu (Philadelphia, USA), Maria-Luz Couce (Santiago de Compostela, Spain), Apolline Imbard (Paris, France), Stefan Kölker (Heidelberg, Germany), Viktor Kozich (Prague, Czech Republic), Karolina Stepien (Manchester, UK) and Ida Schwartz (Porto Alegre, Brazil).

This is E-HOD

European network and registry for homocystinurias and methylation defects. Its aim is to improve the health of children, adolescents and adults affected with these rare disorders.
E-HOD has been funded by the European Commission through its Public Health and Consumer Protection Directorate (DG SANCO), PHEA programme (more information).
