The NSUN5 gene rs1880948 A>G polymorphism and neuroblastoma risk in Chinese children.

Background: Neuroblastoma (NB) is the most common extracranial solid tumor in children. The 5-methylcytosine (m5C) modification gene NSUN5 polymorphisms may serve as promising molecular markers for identifying populations susceptible to NB. Method: TaqMan probes were used to genotype NSUN5 single nucleotide polymorphisms (SNPs) in 402 NB patients and 473 healthy controls. A logistic regression model was applied to calculate the odds ratio (OR) and 95% confidence interval (CI) to evaluate the association between genotype polymorphisms and NB susceptibility. The analysis was further stratified by age, gender, tumor origin site, and clinical stage. Conclusion: In summary, our study indicates that the selected NSUN5 rs1880948 A>G polymorphisms may not be associated with neuroblastoma susceptibility. However, further studies with larger sample sizes and additional potentially functional polymorphisms are needed to validate these results.
