Our results showed that the immunotherapy-naive patients with MG had lower SI and TS levels than the healthy individuals, but they had similar Tf, TIBC, and ferritin levels to the healthy individuals, which indicated that iron inadequacy and inflammation coexisted in the patients with MG because when iron inadequacy and inflammation coexist, both of them would lead to decreased SI and TS, while their effects on Tf, TIBC, and ferritin levels might be offset by each other. The gene discussed is TF; the disease is myasthenia gravis.
