Abstract:
Objective: To assess the association of three new single nucleotide polymorphism (SPN) sites of the transforming growth factor β1 (TGF-β1) gene, which is prevalent in Asia, with the susceptibility to the chronic hepatitis B infection-related liver disease. Methods: The genomic DNA of 129 cases suffering from the chronic HBV peripheral blood infection (74 cases with chronic type B hepatitis, 41 cases with liver cirrhosis and 14 cases with liver cancer) as well as 41 healthy volunteers were prepared. The genotypes of the TGF-β1 gene at rs2241715, rs2241716 and rs4803455 sites were detected by an allotype-specific PCR method. Results: There was a significant difference in the genotypes for rs2241715 and allele frequencies between healthy volunteers and patients with chronic type B hepatitis, liver cirrhosis, and liver cancer (P < 0.05). The individuals with rs2241715 T/T genotype had a 2.974-fold increased risk for developing chronic type B hepatitis (95% CI = 1.209-7.314, P =0.018) and 3.228-fold increased risk for developing liver cirrhosis (95% CI = 1.201-8.675, P = 0.020), while no significant correlation was observed in both genotypes and allele frequencies at rs2241716 and rs4803455 sites. Conclusion: The TGF-β1 rs2241715 T/T genotype: a predisposing factor for the chronic HBV infection-related diseases.
