The presence of iron overload was suggested by elevated serum ferritin levels, transferrin saturation, and the patient's clinical presentation, prompting further investigation into the possibility of hemochromatosis (Table 1). His blood tests showed serum ferritin at 520 ng/mL, transferrin at 1.16 g/L, and transferrin saturation at 71%. This evidence concerns the gene TF and hemochromatosis type 1.
