Mitochondrial DNA in Blood of Friedreich Ataxia Patients May Be a Biomarker, Study Suggests
People with Friedreich ataxia have lower than usual levels of cell-free mitochondrial DNA circulating in the bloodstream, but higher levels of nuclear DNA, a finding that might result in new biomarkers to monitor these patients in clinical trials. Research in Friedreich ataxia would benefit from the existence of a non-invasive biomarker of…
