We found no significant association between the homozygous risk allele (G) of STAT4 and HCC development in either population, with odds ratios (OR) for GG versus TT of 0.85 (CI: 0.48–1.52, p = 0.58) and 0.81 (CI: 0.34–1.93, p = 0.67) for Latin Americans and Europeans respectively. The gene discussed is STAT4; the disease is hepatocellular carcinoma.
