In a previous survey in the northern regions of Cameroon, where the prevalence of current or recent malaria was ~30%, the difference between iron deficiency as measured by inflammation-adjusted ferritin compared to elevated sTfR was large (~35% based on low ferritin vs. ~85% based on elevated stfR)[28], possibly reflecting the effects of malaria-induced anemia on sTfR concentrations. This evidence concerns the gene TFRC and Iron deficiency anemia.
