Biomarkers in Friedreich’s Ataxia


The purpose of this research study is to find out what the best tests and evaluations are for measuring the effects of Friedreich’s ataxia on the body, to help us to design clinical trials.


You will be asked to complete a variety of tests to measure your muscle function, your brain function, and your heart function. This testing will occur over the course of 1 to 2 days, and you may be asked to repeat some tests over those 2 days in order to see if they give the same results.


  • 8-70 years old
  • Genetic diagnosis of Friedreich's ataxia by DNA sequencing, mutational analysis or protein assay OR be a healthy subject with no evidence of a neuromuscular disorder
  • Are able to tolerate metabolic exercise testing
  • Are stable on cardiac medication regimen for 3 months prior to screening
