RESUMO
Objective To investigate the relationship on the excision repair cross complementing gene 1(ERCC1)‐4533/8092 site single nucleotide polymorphisms(SNPs) and the susceptibility to hepatocellular carcinoma(HCC) in Guangxi Zhuang population . Methods Polymerase chain reaction‐restriction fragment length polymorphism (PCR‐RFLP) method was used to detect the ER‐CC1‐4533/8092 gene polymorphism in 88 cases with primary liver cancer and 82 cases of normal controls .Results There was no difference in the frequency distribution of ERCC1‐4533 in the case group and the control group ,the frequency distribution of the ERCC1‐8092 in the case group and the control group was different(P< 0 .05) .Compared with ERCC1‐8092 CC ,ERCC1‐C8092 CA/AA had higher risk of primary hepatocellular carcinoma(CA :OR=2 .556 ,95% CI:1 .345 -4 .855;AA :OR= 8 .667 ,95% CI:1 .000-75 .092) .ERCC1‐8092 C allele as a reference ,ERCC1‐8092 A allele can increase the risk of primary liver cancer (OR=2 .387 ,95% CI:1 .428-3 .992) .Conclusion The genetic polymorphisms of ERCC1‐8092 sites are associated with susceptibility to hepatocellular carcinoma in Guangxi Zhuang population .
