Abstract:
Objective To analyze the association of the single nucleotide polymorphism (SNP) of Toll-like receptor 7 (TLR7) and Toll-like receptor 9 (TLR9) with chronic hepatitis C virus (HCV)infection.Methods A total of 150 patients with chronic hepatitis C (CHC) admitted to Renmin Hospital of Wuhan University from January 2011 to May 2012 and 168 healthy controls were enrolled in the study.The genotypes of TLR7 IVS2-151 (rs179009) were detected by Sanger sequencing,and the genotypes of TLR9 T-1486C (rs187084) were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).SPSS 15.0 was used for statistical analysis,and goodness-of-fit test for HardyWeinberg equilibrium was also performed.Results The frequency of TLR7 IVS2-151G was higher in malepatients with CHC than that in male controls (41.4% vs.21.6%,x2 =7.250,P =0.007,OR =0.389,95% CI:0.194-0.781) ; however the female CHC patients had a higher frequency of TLR7 IVS2-151A than the female controls (76.9% vs.63.1%,x2 =7.202,P =0.007,OR =1.942,95% CI:1.192-3.164).No significant difference in the distribution of TLR9 T-1486C (rs187084) gene SNP was observed betweenCHC and control groups (P >0.05).Conclusion TLR7 IVS2-151 (rs179009) is correlated with HCV infection,which may be involved in the pathogenesis of CHC.
