摘要

Introduction: Glioma is one of the most aggressive human tumors; however, little is known about its genetic risk factors. The role of heredity is likely to be explained by combinations of common low-risk variants. Previous studies have indicated that more than 100 single nucleotide polymorphisms (SNPs) are associated with the risk of glioma. Methods: To further investigate how and to what extent these SNPs contribute to glioma susceptibility in a Chinese population, we analyzed 43 SNPs of 226 glioma patients and 254 normal people in order to evaluate the associations between SNPs and the risk of glioma. Results: Overall, we found three protective alleles for glioma in patients: the allele 鈥淕鈥?of rs1801275 in the IL4R gene by allele model (odds ratio [OR], 0.71; 95%confidence interval [CI], 0.50-0.99; P = 0.04) and dominant model (OR, 0.67; 95%CI, 0.46-0.99; P = 0.04) analysis respectively, the allele 鈥淭鈥?of rs17748 in the TREH gene by recessive model (OR, 0.48; 95%CI, 0.23-1.01; P = 0.05) analysis, and the allele 鈥淕鈥?of rs6470745 in CCDC26 gene by recessive model (OR, 0.48; 95%CI, 0.26-0.89; P = 0.02) analysis. Conclusion: This study provides evidence for three glioma susceptibility genes - TREH, IL4R and CCDC26 - in a Chinese population; this may shed light on molecular markers of glioma susceptibility and could therefore be used as a diagnostic and prognostic marker for glioma patients in clinical study.
