For many years, EuroClonality has supported laboratories around the world with expert advice for difficult clonality testing cases, based on the EuroClonality/BIOMED-2 assays (GeneScan fragment analysis). This has helped professionals tackle technical challenges and interpret complex results, all in the spirit of EuroClonality aims: collaboration and knowledge sharing.

Today, we celebrate the birthday of Professor Jacques J.M. van Dongen. He turned 70 yesterday, but is still the driving and binding force behind the ESLHO foundation and the consortia EuroFlow, EuroMRD and EuroClonality. We surprised him with some very special gifts. We asked all participating institutes (>100!) to send him a personal birthday card. This resulted in a very diverse and heartwarming collection of cards in all languages, with music, portraits and crafty little artworks. They were presented to him in one big box. A unique gift and a wonderful token of appreciation!

Last week, on April 3rd and 4th, 2025, the EuroClonality-NGS Working Group came together in Prague for a meeting. Participants shared updates on their latest research, and in-person attendees had the opportunity to have in-depth discussions and brainstorming sessions. The collaboration between the different institutes continues to be of great value, and significant progress was made towards the continuation of several research initiatives.
