Abstract

To determine whether three of CYP1B1 single nucleotide polymorphisms, c.142C>G, c.355G>T and c.1294C>G are associated with a lung cancer risk. A total of112 lung cancer patients and 100 controls were genotyped using the RFLP-PCR. In the c.142C>G polymorphisms, G allele was more frequent in lung cancer patients than in controls (p<0.001), while in the c.1294C>G polymorphisms, C allele was more frequent in lung cancer patients, than in controls (p=0.012). In the c.355G>T polymorphism, the distribution of alleles in both analyzed groups was similar. The GTC haplotype turned out to be correlated with the increased lung cancer risk, compared with the most common CGG haplotype (OR: 2.38; p=0.001). CYP1B1 gene polymorphisms appear to influence lung cancer susceptibility.
