Abstract: BACKGROUND AND AIM: To investigate polymorphisms of CYP3A7 gene of population in Guangxi with heavy aflatoxin B1 (AFB1)contamination, and the relationship between CYP3A7 genotypes and susceptibility of hepatocellular carcinoma (HCC). MATERIALS AND METHODS: Single nucleotide polymorphisms of CYP3A71A and 1C were analyzed in 210 cases and control samples (97 HCC, 38 HBV_positive but with no other disease and 75 HBV_ negative no disease) using the polymerase chain reaction_restriction fragment length polymorphism assays. RESULTS: All of the samples were CYP3A71A/1A genotype ,CYP3A71C allele was not detected in this cohort of Guangxi population. CONCLUSION: CYP3A71C allele was not detected in this cohort,suggesting that CYP3A7 might have a small influence on the development of AFB1_related HCC.
