The aim of this study was to examine whether <i>STAT1</i> gene polymorphisms are associated with the risk of hepatocellular carcinoma (HCC). <i>Methods:</i> Ten single nucleotide polymorphisms in the <i>STAT1</i> gene were genotyped by TaqMan assays in 469 HCC cases and 558 age-, sex- and HBsAg-matched controls in a Chinese population. <i>Results:</i> Minor allele homozygous genotypes at rs867637 (9,046 bp 3′ of STP A>G), rs3771300 (IVS24–153T>G), and rs2280235 (IVS20–103G>A), compared with their homozygote genotypes of common alleles, were associated with 1.6- (95% CI 1.1–2.3), 1.6- (95% CI 1.1–2.4), and 1.4-fold (95% CI 0.95–1.9) increased risk of HCC, respectively. The GGA haplotype, comprised of risk alleles at rs867637, rs3771300 and rs2280235, conferred a 1.2-fold (95% CI 1.0–1.5) increased risk of HCC, as compared to the most common haplotype of ATG. Diplotype GGA/GGA conferred a 1.6-fold (95% CI 1.0–2.5) increased risk of HCC compared with diplotype ATG/ATG. <i>Conclusion:</i> Our results demonstrate for the first time that polymorphisms in the <i>STAT1</i> gene are associated with HCC susceptibility. 2010-08-27 00:00:00 Hepatocellular carcinoma Polymorphisms STAT1
