The relative FXN expression in the patients was found to be correlated with the levels of MDA and ferritin but not correlated with transferrin saturation. The elevation of FXN expression in the reticulocytes of these patients seems to be linked to oxidative stress and iron status. Findings also suggest that FXN expression is at least partially regulated by the mitochondrial demand for iron for haem synthesis.
