Therefore, in this study, we aimed to explore whether the H19 polymorphisms were related to the susceptibility of HCC. Materials and Methods: A case-control study of 625 cases and 621 controls was conducted to investigate genetic associations of three potentially functional variants in H19 (rs2839702, rs2067051 and rs2075745) with HCC risk in a Southern Chinese population. Results: After adjustment for age, gender, smoking status, drinking status, HBsAg status, and family history of cancers, three H19 polymorphisms were not associated with HCC risk under any genetic models. The odds ratio (OR) per risk allele for HCC was 1.03 (95% confidence interval [95% CI] = 0.94–1.13) for rs2839702, 1.05 (95% CI = 0.96–1.16) for rs2067051, and 1.04 (95% CI = 0.95–1.14) for rs2075745, respectively. No significant associations were also observed in the stratified analysis, haplotype analysis and combined effect analysis. Conclusions: Our study indicated that no association of polymorphisms (rs2839702, rs2067051 and rs2075745) in long non-coding RNA H19 with HCC. Further larger population-based case-control study and a global view to the genetic component of H19 would be required to identify the causal genetic polymorphisms for HCC.
