Diagnostic Screening Tests and Potential Biomarkers in Mitochondrial Myopathies
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.

The purpose of this study is to develop simple diagnostic screeningtests and investigate potential biomarkers for identifying patients with abnormalities of mitochondrial function, which also can be used as outcome measures in future clinical trials. The study will investigate two submaximal tests: a submaximal handgrip test and a walking test. Furthermore investigators will investigate Acyl-carnitine profiles and GDF-15 levels in patients with mitochondrial myopathy.
