Non-OXPHOS diseases may present with a CoQ deficiency, such as in multiple Acyl-CoA dehydrogenase deficiency (2 patients), apraxia with oculomotor ataxia and Friedreich’s ataxia. However, decreased levels of CoQ seemed not to be a consistent feature in some of these conditions given that patients who had the same disease were found to have both normal or reduced CoQ levels.
