Pehlivan et al found no association between TNF‐α rs1800629, IL‐10 rs1800872, rs1800871, and rs1800896, IFN‐γ rs2430561, and TGF‐β1 rs1800470 (codons 10 and 25) polymorphisms and OS in their Turkish CML patients,13 being therefore in line with our observations. This evidence concerns the gene IFNG and chronic myelogenous leukemia, BCR-ABL1 positive.
