The article analyses 65 projects funded by the European Joint Programme for Rare Diseases (EJP RD) to identify ethics and regulatory issues encountered by researchers and to describe the guidance provided through the programme’s Ethics Follow-up process. Most projects addressed human participants and personal data, including genetic data, biospecimens, children and non-EU country involvement. The abstract reports that EJP RD guidance supported ethics compliance, while regulatory procedures were often overlooked, highlighting a need to strengthen regulatory awareness in rare disease research.
