The International Network for Undiagnosed Diseases (UDNI) was established in 2014 as a collaborative initiative spanning multiple countries. Its primary mission is to improve diagnostic rates for individuals living with undiagnosed conditions. The UDNI brings together clinical and research centers renowned for their expertise in rare diseases. This global network fosters interdisciplinary collaboration, facilitates knowledge sharing, and accelerates the translation of research findings into clinical practice to improve patient care. Since its inception, the UDNI has already organized 13 successful conferences, serving as a platform for sharing breakthroughs and fostering collaboration. For the first time, the UDNI Conference will take place in the Southern Hemisphere, hosted in Latin America’s dynamic and safe Barra da Tijuca neighborhood, in Rio de Janeiro, Brazil. This vibrant area is known for its stunning beaches, modern amenities, and welcoming atmosphere, making it an ideal setting for the conference. Rio de Janeiro, Brazil's former capital, is internationally celebrated for its breathtaking natural beauty, iconic landmarks, and rich cultural heritage.
