A combined conference on rare diseases was organized by ERICA and EJP on November 21, 2023, with the aim of showcasing their work packages and discussing how they could contribute to the future progress of ERNs. Ideas for their budget for various task packages were addressed, along with further details on ERDERA and JARDIN activities. ERNs were given an opportunity to hear about the goals of collaboration from representatives of the RDCRC in the USA, the Maternal Infant Child & Youth research (RareKids CAN Network Structure) network in Canada, and MICYRN: Canadian National Mirror Group.
