OBJECTIVE: To explore the correlation of the gene polymorphisms of Toll-like receptor 2 ( TLR2) and TLR4 with the susceptibility and recurrence of condyloma acuminatum (CA).
METHODS: Using Snapshot, we detected the gene polymorphisms of TLR2 597(T/C), 1350(T/C), 15607(A/G), and 2258(G/A) and TLR4 896(A/G) and 1196(C/T) in the peripheral blood of 140 CA patients and 105 HPV-negative controls. We made comparisons between the CA patients and controls as well as between the cases of recurrent CA and those of non-recurrence at 6 months after treatment.
RESULTS: There were 72, 48, and 20 cases of genotype TT, TC, and CC of TLR2 597 (T/C), respectively, in the CA patients, as compared with 71, 31, and 3 cases in the controls. The gene frequency of mutant C was 31. 43% in the patients, significantly higher than 17.62% in the controls (χ2 = 12.04, P < 0.01), and it was 38.68% in the recurrent cases, remarkably higher than 27.01% in the non-recurrent cases (χ2 = 4.16, P < 0.05). There were 74, 49, and 17 cases of genotype TT, TC, and CC of TLR2 1350( T/C), respectively, in the CA patients, as compared with 73, 29, and 3 cases in the controls. The gene frequency of mutant C was 29. 64% in the patients, significantly higher than 16. 67% in the controls (χ2 =11.05, P < 0.01), and it was 36.79% in the recurrent cases, markedly higher than 25. 29% in the non-recurrent cases (χ2 = 4.18, P < 0.05). There were 44, 66, and 30 cases of genotype AA, AG, and GG of TLR2 15607(A/G), respectively, in the CA patients, as compared with 26, 58, and 21 cases in the controls. There was no significant difference in the gene frequencies of mutant G between the two groups (χ2 = 0.33, P > 0.05). No mutant genes of TLR2 2508 (G/A) or TLR4 896(A/G) and 1196(C/ T) were detected in either the CA patients or the controls. Linkage disequilibrium analysis showed a tight linkage between TLR2 597 (T/C) and 1350(T/C) (D' = 1, r2 = 0.93).
CONCLUSION: TLR2 597(T/C) is tightly linked to 1350(T/C), which is correlated with both the susceptibility and the recurrence of condyloma acuminatum.
