AbstractOur purpose was to investigate the possible associations between N-acetyltransferase-2 (NAT2) gene polymorphisms and the risk of acute myeloid leukemia (AML) in Chinese Han population.A case-control study was conducted including 98 AML cases and 112 healthy controls. NAT2 gene 2 polymorphisms rs1799930 and rs1799931 were genotyped using direct sequencing. Chi-square test was performed to compare the genotype and allele distribution differences between groups. Odds ratio (OR) with 95% confidence interval (CI) was calculated to estimate the association between NAT2 gene polymorphisms and AML onset.A remarkable decrease trend of rs1799931 GA genotype was detected in AML patients compared with controls, whereas the ancestral GG genotype frequency increased in cases (P < .05). And the mutant A allele of rs1799931 significantly reduced the risk of AML by 0.585-fold versus the ancestral G allele carriers (OR = 0.585, 95% CI = 0.361-0.950). But the distributions of rs1799930 genotype and allele were similar between groups (P > .05).Our findings suggested that NAT2 gene polymorphism rs1799931 was associated with decreased risk of AML and was likely to be a protective factor against AML development.
