Abstract

Purpose: Genetic factor is a risk factor in glioma occurrence. This study was designed to detect the effect of ADCY9 polymorphisms on glioma risk and prognosis.

Methods: We performed a case-control study of 1080 participants (584 cases and 496 controls) to assess the relationship of ADCY9 polymorphisms with the risk and prognosis of glioma among the Chinses Han population. Odds ratios (ORs) and 95% confidence intervals (CIs) were computed to evaluate the relationship between ADCY9 variants and glioma risk. The correlation of SNPs with survival was analyzed by the Cox regression model.

Results: Our study showed that rs2230742 and rs2531992 polymorphisms played protective roles in glioma susceptibility (OR 0.65, p = 0.001; OR 0.73, p = 0.038, respectively). While rs2230742 significantly increased the susceptibility of III-V grade glioma patients (OR 1.50, p = 0.036). Haplotype analysis revealed that Crs879620Ars2230742Ars2230741 haplotype was related to a significantly decreased glioma risk (OR 0.65, p = 0.002). Notably, rs2531995 and rs879620 polymorphisms significantly enhanced death risk in high-grade glioma patients (hazard ratio [HR] 1.36, p = 0.041; HR 1.37, p = 0.042; respectively). For rs2230742 and rs2531992 SNPs, glioma patients had a worse prognosis (HR 2.30, p = 0.021; HR 2.30, p = 0.021; respectively). We further observed that age, chemotherapy, and surgical scope can affect the glioma prognosis.

Conclusion: We firstly studied the association of ADCY9 variants with glioma risk and prognosis, which might give scientific evidence for exploring the molecular mechanism of glioma.
