About the study

The PIONEER study is a prospective, natural history study dedicated to characterizing the clinical progression of POLG-related disorders. The research aims to bridge the gap between genetic diagnosis and drug development by mapping how these rare mitochondrial conditions evolve over time. By observing the disease's natural trajectory through a multi-center approach, The study identifies critical clinical milestones that serve as a foundation for evaluating therapeutic efficacy and future therapeutic interventions
