The results showed a significant positive association between rs730437/rs845552 and glioma risk in Asians, and a significant negative association between them in Caucasians.
These data suggest that five EGFR SNPs (rs11506105, rs3752651, rs1468727, rs845552 and rs730437) correlated with glioma patient prognosis, and should be furthered validated in studies of ethnically diverse patients.
For rs730437, we found both the AA genotype (p=0.011) and A allele frequency (p=0.003; OR=0.703; 95% CI: 0.558-0.886) were significantly lower in the glioma patients than in the control subjects, respectively.
We identified two susceptibility tSNPs in the EGFR gene that were potentially associated with an increased risk of glioma (rs730437, p = 0.016; OR: 1.32; 95%CI: 1.05-1.66 and rs1468727, p = 0.008; OR: 1.31; 95%CI: 1.04-1.65).
