In the current study, no association was observed between the other five polymorphisms analyzed (GSTT1 null genotype, GSTP1 Ile105Ala, CAT C262T, GPX1 Pro198Leu, and MnSOD Ala16Val) and the occurrence of ACA in CML patients (P value > 0.05 for all comparisons performed). Here, CAT is linked to chronic myelogenous leukemia, BCR-ABL1 positive.
