About this trial
This international, multi-center, multi-modal and prospective observational study aims to determine the phenotypic spectrum and the natural progression of the RFC1 repeat expansion disease, and to seek and validate digital, imaging, and molecular biomarkers that aid in diagnosis and serve as outcome measures in future clinical trials of this novel, but frequent ataxia with late adult-onset.
