The invention relates to a kit for predicting nasopharynx cancer onset risk, and a corresponding gene chip. The kit comprises a PCR (Polymerase Chain Reaction) amplification primer and a single base extension primer which are used for detecting 7 SNP (Single Nucleotide Polymorphism) loci of personal genome, wherein the 7 SNP loci are rs1412829, rs1572072, rs28421666, rs2860580, rs2894207, rs6774494 and rs9510787; the kit further comprises a PCR amplification primer and a single basic extension primer which are used for detecting 4 SNP loci of personal genome, wherein the 4 SNP loci are rs2853668, rs31489, rs402710 and rs4635969; the kit further comprises a nested PCR amplification primer for detecting a single nucleotide polymorphism locus G155391A with EB (Elzatein-Barn) virus subtype specificity related to nasopharynx cancer. The gene chip comprises upstream and downstream primers and probes for detecting 11 SNP loci of personal genome, and upstream and downstream primers and probes for detecting a single nucleotide polymorphism locus G155391A with the EB virus subtype specificity related to nasopharynx cancer, wherein the 11 SNP loci are rs1412829, rs1572072, rs28421666, rs2860580, rs2894207, rs6774494, rs9510787, rs2853668, rs31489, rs402710 and rs4635969.
