PURPOSE: To evaluate the association between glutathione S-transferase Omega (GSTO) genes polymorphism and the susceptibility of acute lymphoblast leukemia (ALL). METHODS: The polymorphism of GSTO1 and GSTO2 genes were analyzed in 99 ALL patients compared with 100 healthy children by PCR-based restriction fragment length polymorphism (RFLP) analysis. RESULTS: GSTO1*A140D polymorphism was significantly associated with susceptibility to ALL (OR = 2.24, 95% CI = 1.16-4.35, P = 0.009) whereas, GSTO2*N142D genotype was significantly interacted with high risk group of childhood ALL (OR = 5.52, 95% CI = 1.72-17.71, P = 0.004). CONCLUSION: This study revealed gene polymorphism in glutathione S-transferase Omega class may be a risk factor to the development of acute childhood lymphoblastic leukemia.
