RESUMO
Objective To study the relationship between genetic polymorphisms of CYP2E1 and the susceptibility of the acute leukemia in Gansu population. Methods The C609T polymorphism of CYP2E1 gene was detected by polymerase chain reaction-ligase detection reaction (PCR-LDR) and 1∶1 matched casecontrol method in 100 healthy persons (control group) and 100 patients with acute leukemia (AL group).Results The C2 allele genotype and C1C2/C2C2 genotype of CYP2E1 gene occurred more frequently in AL group (13.5 % and 22 %, respectively) than those in control group (10.5 % and 19 %, respectively), however,both differences showed no statistical significant. Further stratified analysis, the C1C2/C2C2 genotype of CYP2E1 gene occurred more frequently in AML group (27%) than that in control group (19 %), but difference had no statistical significant, too. The occurrence frequency of the C2 allele genotype and C1C2/C2C2 genotype of CYP2E1 gene showed no significant difference in ALL group and control group (x2=0.446, P =0.504>0.05). Conclusion Genetic polymorphisms of CYP2E1 don't correlated to susceptibility of acute leukemia(AML and ALL) in Gansu population.
