The DMRF organized a scientific workshop on the Mechanisms of Reduced Penetrance in Dystonia in Helsinki, Finland on June 19-21. Dystonia penetrance refers to the percentage of individuals with a specific genetic mutation who develop dystonia. The workshop was co-chaired by Christine Klein, MD from the University of Lübeck and Christopher Pearson, PhD from the University of Toronto and included leading clinicians and researchers in the field. The goal of the meeting was to deepen scientists’ understanding of the causes and mechanisms of reduced penetrance in dystonia, as well as evaluate existing and identify new research strategies.
