Wilhelm Foundation has organized twelve International Conferences on Rare and Undiagnosed Diseases in collaboration with Dr. Gahl, the host country's doctors and UDNI. The most recent Conference was the 12th Conference, taking place on October 22-23 2023, in Tbilisi Georgia.
Conference's primary goal is to spread awareness of the Undiagnosed Diseases Program (UDP) and Undiagnosed Diseases Network International (UDNI) to get more specialists to help solve the undiagnosed diseases. Another very important feature of the congresses is that the specialists address one of their unresolved diseases and ask the participants for help in solving the mystery, which is the Wilhelm Foundation's intention with the World Congresses.
