Abstract:

Objective To investigate the association between interferon gamma(IFN-γ)polymorphisms [rs2430561(+874T/A) and rs1861494(+2109A/G)] and the susceptibility to nasopharyngeal carcinoma(NPC). Methods A total of 150 NPC patients and 150 healthy subjects were enrolled. IFN-γ +874T/A and +2109A/G were determined by polymerase chain reaction(PCR)-sequence-specific primer(SSP) and PCR-restriction fragment length polymorphism(RFLP),respectively. Results Compared with AA genotype,the risk of rs2430561 +874T/A TT genotype was decreased [odds ratio(OR)=0.132,95% confidence interval(CI) 0.022-0.800,P=0.028]. However,there was no statistical significance for rs1861494 +2109A/G(P>0.05). Conclusions IFN-γ rs2430561 +874T/A polymorphisms are associated with the susceptibility to NPC.
