Out of 1347 participants, (29.6%) had HWA (Hb > 12 g/dL, Fe < 30ng/mL), (30.1%) were normal (Hb > 12 g/dL, Fe > 30 ng/mL), (3.49%) had hyperferritinemia (SF >120ng/ml), (24.6%) had iron deficiency anemia (Hb < 12 g/dL, Fe < 30 ng/mL) and (12.2%) had non-iron deficiency anemia (Hb < 12g/dL, Fe >30 ng/mL). Here, GSTM1 is linked to isolated hyperferritinemia.
