ERN-EYE (represented by Hôpitaux Universitaires de Strasbourg) will transform the current Rare Eye Disease (RED) landscape in Europe, which consists of >24000 patients treated in our centres, suffering from >1000 ophthalmologic conditions, by developing an interoperable, sustainable and high-quality core patient registry for RED (i.e. REDgistry). With REDgistry, we will tackle the issues that impair the currently operational RED registries in the 13 ERN-EYE countries: lack of shared standards, absence of cross-registry interoperability, instable funding, legal uncertainty, inconsistent data quality, and absence of data sharing procedures.

Hence, we aim at i) creating a harmonised high-quality GDPR-compliant registry developed in accordance to the FAIR principles (i.e. Findable, Accessible, Interoperable and Reusable), ii) entering the ad hoc cases while controlling and evaluating the data, iii) ensuring its long-term sustainability, iv) engaging the key REDgistry stakeholders. These objectives will be achieved by 1) establishing a sound governance and long-term sustainability strategy, 2) developing and implementing the IT platform, and 3) entering, cleaning and evaluating the data.
REDgistry will enable the performance of epidemiology studies on RED, improve identification of currently undiagnosed RED patients, increase patient access to novel treatments and clinical trials, and enhance RED research capabilities through international cooperation, knowledge sharing and the future development of interoperable disease-specific registries. The final outputs of the REDgistry project will be an operational basic registry with a common dataset enrolled in the European Rare Disease Registry Infrastructure, a specific ophthalmic dataset, an established governance structure for the registry, a report on the preliminary epidemiology of RED in Europe, a dissemination & communication plan to raise awareness of REDgistry, and a sound economic plan to ensure its sustainability.

The European Registry for Rare Bone and Mineral Conditions (EuRR-Bone) aims to realise improved, harmonised healthcare for people living with rare bone and mineral conditions (RBMCs) across Europe. Our focus includes over 150 severe rare bone diseases that affect cartilage, bones and dentin and more than 40 severe rare diseases affecting phosphate and calcium metabolism. In this project, we will establish the first pan-European registry in RBMCs.

RBMCs constitute a complex group of diseases with evident need for better and more harmonised care. The lack of natural history data is significant, and the quality of care and expertise varies across regions and in many countries is still unclear. Depending on first symptoms and local healthcare processes, a wide variety of healthcare specialists can be involved in the process. Until recently, there was limited cross-disciplinary alignment: each discipline had its own network, conference, guidelines and even registries. The European Reference Network on Bone Disorders (ERN BOND) has taken the lead to better organise the field, to harmonise and improve RBMCs healthcare.
Specifically, in this project, a core group of ERN BOND healthcare providers, affiliated centres and experts will:

• Establish a centralised registry for RBMCs within the scope of ERN BOND in collaboration with the already established European Registry for Rare Endocrine Conditions, EuRRECa, covering a core longitudinal minimal data set to capture their natural history from both clinician and patient perspectives.
• Establish four disease specific modules on Fibrous Dysplasia/McCune Albright syndrome (FD/MAS), Osteogenesis Imperfecta (OI), Rare Hypophosphatemia and Achondroplasia (ACHO), that capture genetic, clinical and patient related outcome measures in a scalable manner to other RBMCs.
• Provide a platform that enables detailed local, disease-specific registries on rare bone and mineral disorders to connect to EuRR-Bone.

Within our EPICARE network, we want to build a useful registry for all patients with rare and complex epilepsies. This registry will contain the common data elements, as proposed by EU RD platform, as well as key epilepsy data fields such as etiology and treatment modalities. The existing pilot version of our registry will be updated and put an a REDcap platform. Pseudonymisation will be done with the EUPID tool and data fields will be FAIRified, so that interoperability with other registries and database will be possible. Links with Orphanet, WHO and genetic databases will be installed. After a pilot trial, the registry will be rolled out in all EPICARE centers. In a next phase, collaborations with other partners such as RD NEXUS and patient organisations (EPAG) will be established so that the EPICARE registry will become a pivotal element in all EPICARE activities. The EPICARE registry, as well as the links with other ERN and non-ERN registries and databases, will allow us to identify where in Europe the patients are located with rare and complex epilepsies and will make dedicated research, optimisation of diagnosis and treatment possible.
