Our study suggested that the presence of 'C' allele of rs4646903 (T>C) showed no risk and 'G' allele of rs1048943 (A>G) might be a leading allele to cause increased cervical cancer susceptibility due to significant association of CYP1A1m2 gene polymorphism.
An association with cervical cancer and high-grade dysplasia was found for the rare homozygous CC genotype (rs4646903) in CYP1A1 (odds ratio [OR], 8.862).
