ABSTRACT
<p><b>OBJECTIVE</b>To explore the relationship between genetic polymorphisms of CYP-1A1 and CYP2D6 and risks of chronic benzene poisoning (BP).</p><p><b>METHODS</b>A case control study was conducted. 152 BP patients and 152 workers occupationally exposed to benzene without poisoning manifestations were involved. Polymerase chain reaction followed by restriction fragment length polymorphism (PCR-RFLP) technology was used for detecting the single nucleotide polymorphisms (SNPs) of MspI in the non-coding region of CYP-1A1 gene and c.188, g.212 position in the first extron of CYP2D6 gene.</p><p><b>RESULTS</b>The individuals with CYP1A1 MspI T/T genotype had a 1.32 times (95% CI 1.05 approximately 1.65, P = 0.02) increased risk of BP compared with those carrying T/C and C/C genotypes. In no-smoking population, there was a 1.56 times (95% CI 1.15 approximately 2.12, P = 0.003) increased risk of BP for subjects carrying CYP1A1 MspIT/T genotype compared with those carrying T/C and C/C genotypes. The individuals carrying CYP2D6 c.188 C/C or C/T genotype had a 1.23 times (95% CI 1.05 approximately 1.42, P = 0.01) increased risk compared with those carrying T/T genotypes. In no-smoking population, there was a 1.23 times (95% CI 1.04 approximately 1.47, P = 0.01) increased risk of BP for subjects carrying CYP2D6 c.188 C/C or C/T genotypes compared with those carrying T/T genotype. The single nucleotide polymorphism of g.212 position in the first extron of CYP2D6 gene had not been validated.</p><p><b>CONCLUSION</b>The individuals with CYP2D6 c.188 C/C, CYP2D6 c.188 C/T and CYP1A1 MspIT/T genotypes tend to be more susceptible to benzene toxicity.</p>
