General objective E-HOD
Promote health for children, adolescents and adults affecte with HCU and MD Reduce variation between countries Improve access to medical expertise and information for these rare diseases
11
Scope & objectives Improving knowledge on HCU and MD through collection of clinical data into a registry Developing diagnosis and clinical care recommendations Evaluating newborn screening (NBS) programme with recommendations European patient registry to describe the natural history, epidemiology, and current diagnostic and therapeutic strategies for homocystinurias and methylation defects; including data following patients picked up on NBS programmes To provide European evidence-based consensus care protocols for all diseases To evaluate the success rate of newborn screening programmes for homocystinuria with recommendations

75 clinical collaborating partners 7 other collaborating partners
The network has expanded from 32 partners (13 associated and 19 collaborating) in 15 European countries to a group of 62 partners (an additional 30 collaborating partners) in 25 countries. The network includes clinicians, scientists, dietitians, patient organisations and industry representatives. Representatives of other consortia have become members of E-HOD including those of the SSIEM adult metabolic group, the SSIEM dietitians’ group thereby linking E-HOD with other organisations dedicating to improved health for patients with rare UCDs and OADs. 13 associated partners 75 clinical collaborating partners 7 other collaborating partners from 28 countries
