These findings auger well for using frataxin levels measured by the validated stable isotope dilution ultrahigh-performance liquid chromatography–multiple reaction monitoring/mass spectrometry assay to monitor therapeutic interventions and the natural history of FRDA. Our study also illustrates the utility of using whole blood for protein disease biomarker discovery and validation.
