Patients with AML-MRC had significantly older age (p<0.001), lower hemoglobin (Hb) (p<0.001), lower WBC count (p<0.001), and higher male-to-female ratio (p=0.006) than the AML-NOS group, while no significant differences were detected in terms of platelet count (p=0.462) and lactate dehydrogenase (LDH) (p=0.139). The gene discussed is GSTM1; the disease is acute myeloid leukemia.
