Association between epidermal growth factor +61 G/A polymorphism and glioma risk in a Chinese Han population

J Int Med Res. 2010 Sep-Oct;38(5):1645-52. doi: 10.1177/147323001003800509.

Abstract

The association between the +61 G/A polymorphism of the epidermal growth factor (EGF) gene and glioma risk remains controversial and unclear. The objective of this study was to investigate the association between the EGF +61 G/A polymorphism and glioma risk in a Chinese Han population. Peripheral blood samples were extracted from 160 glioma patients and 320 control subjects. Genotyping was performed using a polymerase chain reaction-restriction fragment length polymorphism method. Glioma patients had a significantly higher frequency of the AA genotype (odds ratio [OR] 1.93, 95% confidence intervals [CI] 1.08, 3.44) than control subjects and the frequency of the AA genotype was significantly higher in glioblastoma patients than in patients with other gliomas (OR 2.19, 95% CI 1.05, 4.57). Patients with grade IV gliomas had a significantly higher frequency of the AA genotype (OR 2.25, 95% CI 1.08, 4.71) than patients with lower grade gliomas. This study demonstrated that the EGF +61 AA genotype is associated with an increased risk of glioma in a Chinese Han population.
