The frequencies of the genotypes were detected by PCR and PCR-RFLP techniques.ResultsThe variation frequencies of CYP1A1 gene (Msp I polymorphisms, site 3801T-C variation) in ALL and ANLL groups were 74.1% and 70.8% respectively which were higher than 63.3% appeared in the healthy controls. However, the differences between patients (ALL or ANLL) and healthy controls were not statistically significant (P > 0.05 for both). The null genotype of GSTM1 (GSTM1 -/-) in ALL group was 60.7%, which was not significantly different from the controls (55.4%). However, GSTM1 -/-genotype in ANLL group was 68.3%, significantly different from the controls (P < 0.05). The null genotypes among GSTT1 (GSTT1 -/-) in ALL, ANLL and control group were 50.9%, 55.0% and 49.0% but their differences were not statistically significant (P > 0.05). The incidences of GSTM1 -/- and GSTT1 -/-combined genotype in ALL, ANLL and control group were 33.0%, 40.0% and 27.5%, of which the difference between ANLL group and control group was statistically significant (P < 0.05) and CYP1A1 gene heterozygous mutation type or homozygous mutation type combined with GSTM1 -/- and GSTT1 -/-increased the risk of ANLL (OR value 1.890, 95% CI: 1.084-3.295).ConclusionThese results indicated that both the variation of CYP1A1 gene or GSTT1 -/-genotype alone might not be associated with the susceptibility of acute leukemia while GSTM1 -/- genotype alone or combined with GSTT1 -/- or the 3801 T-C variation of CYP1A1 gene were correlated with ANLL. These findings suggest that GSTM1 - / - genotype alone or in combination with other defective genotypes might serve as risk factors to the etiology of ANLL."xsd:string |
