What procedures and tests diagnose Friedreich’s ataxia syndrome?

The conclusive diagnosis can be made by genetic testing for the FXN gene mutation. An electromyogram (EMG), which measures the electrical activity of muscle cells, and nerve conduction studies, which assess the speed of nerve signaling, are two further procedures to examine nerve and muscle function that are occasionally used to determine the diagnosis. To rule out alternative causes of the symptoms, imaging techniques like CT or MRI scans may be utilized.
