Neuroblastoma is a heterogeneous cancer frequently occurring in childhood. Germline mutations of oncogene are implicated in several types of cancer. However, whether common single nucleotide polymorphisms (SNPs) in gene are associated with neuroblastoma risk has received relatively few attentions. In this multi-center study, we aimed to elucidate the contributing role of SNPs in neuroblastoma risk. We successfully genotyped three potentially functional SNPs (rs1136410 A>G, rs2666428 T>C, rs8679 A>G) in 469 neuroblastoma cases and 998 controls. We did not detect any significant association between the analyzed SNPs and neuroblastoma risk in single SNP analysis. However, stratified analysis revealed that rs1136410 AG/GG carriers were more likely to develop tumors arising from mediastinum (AG/GG vs. AA: adjusted OR=1.65, 95% CI=1.06-2.56, =0.028). Moreover, rs2666428 TC/CC carriers were at significantly lower risk to develop tumors from "other sites" (TC/CC vs. TT: adjusted OR=0.44, 95% CI=0.20-0.96, =0.040). Our findings failed to provide evidence of the conferring role of the gene polymorphisms in the risk of neuroblastoma. Further investigations of the association between gene SNPs and neuroblastoma risk are warranted.
