Effect of miR‐34b/c rs4938723 T > C on pediatric glioma susceptibility

AbstractGliomas, the most common type of primary intracranial tumor, arise from the brain's glial cells and constitute 30% of all brain and central nervous system tumors. MiR‐34b/c plays an important role in colorectal cancer and other cancers, but its role in glioma is unknown. In this study, we attempted to assess the effect of rs4938723 T > C in miR‐34b/c on the susceptibility of glioma Chinese children. Odds ratios and 95% confidence intervals (CIs) were calculated to evaluate the association between the selected polymorphism and glioma susceptibility. Our results showed that there is no significant association between this polymorphism and the risk of glioma in Chinese children. However, stratified analysis showed that the rs4938723 TC/CC genotype significantly reduced the risk of glioma in participants under 60 months of age (adjusted OR = 0.56, 95% CI = 0.35–0.88, p = .013). Overall, our study indicates that miR‐34b/c rs4938723 T > C polymorphism may have a weak influence on glioma susceptibility. Nevertheless, these findings need to be validated in well‐designed studies with larger sample sizes and different populations.
