The Influence of NDRG1 Single Nucleotide Polymorphisms on Glioma Risk and Prognosis in Chinese Han Population

Abstract Background: glioma is a highly fatal malignant tumor with a high recurrence rate. We aimed to determine the association between single nucleotide polymorphisms (SNPs) of NDRG1 and glioma risk and prognosis in the Chinese Han population.Methods: 5 candidate SNPs were genotyped by Agena MassARRAY; logistic regression was used to analyze the association between SNPs and glioma risk; We used multi-factor dimensionality reduction to analyze the interaction of ‘SNP-SNP’; the prognosis analysis was performed by log-rank test, Kaplan–Meier analysis and Cox regression model.Results: our results showed that the rs3808599 was associated with the reduction of glioma risk in all participants (p = 0.024) and the participants ≤40 years old (p = 0.020). rs3802251 may reduce glioma risk in all participants (p = 0.008), the male (p = 0.033) or astrocytoma patients (p = 0.023). rs3779941 was associated with poor glioma prognosis in the all participants (p = 0.039) or astrocytoma patients (p = 0.038). We also found that the key factors for glioma prognosis may include surgical operation, radiotherapy and chemotherapy.Conclusion: this study is the first to find that NDRG1 gene polymorphisms may have a certain association with glioma risk or prognosis in the Chinese Han population.
