The Natural History of Mitochondrial Diseases

This is a 10-year, longitudinal, non-randomised, retrospective and prospective, observational study that will be used to characterise the natural history of primary mitochondrial disease (MITO) in 400 participants and their asymptomatic family members (with no genetic risk), non-MITO healthy controls (100 participants) and form a biobank that can be used in future research using separate ethics approved protocols to identify biomarkers of disease onset and progression.
