Associations of LncRNA H19 Polymorphisms at MicroRNA Binding Sites with Glioma Susceptibility and Prognosis
2020
Abstract Glioma is the most common tumor of the central nervous system; variation in susceptibility and prognosis worldwide suggests that there is molecular and genetic difference among individuals. The H19 gene plays a dual role in carcinogenesis. In this study, associations between H19 polymorphisms and susceptibility as well as prognosis in glioma were evaluated. In total, 605 patients with glioma and 1,300 cancer-free subjects were enrolled in the study. Individuals with the rs3741219 A>G allele were less likely to develop glioma (RR = 0.54, 95% CI: 0.45-0.63, P A and rs2839698 G>A genotypes were not associated with glioma risk. The associations between H19 polymorphisms and prognosis were assessed, including overall survival and progression-free survival. Three focused H19 polymorphisms did not show a significant effect on survival. Further analysis based on false positive report probability had validated this significant results. In the haplotype analysis, individuals with the Grs217727Ars2839698Grs3741219 haplotype were less likely to develop glioma (OR = 0.33, 95% CI: 0.23-0.46, P = 0.02). Overall, carriers of the rs3741219 AG or GG genotype of H19 have a decreased susceptibility to glioma, but polymorphisms in this gene are not related to prognosis.
