The association between tumor necrosis factor receptor 2 gene polymorphism and development of coronary artery disease / 中华检验医学杂志

ABSTRACT

Objective To study the association of biallelic polymorphism at position 196 in exon 6 of tumor necrosis factor receptor 2(TNFR2) gene and coronary artery disease(CAD).Methods A retrospective case control study was designed in this investigation.Patients with angiographically proven CAD (n=142)and coronary atherosclerosis(n=215)were compared to healthy volunteers(n=631). Genotyping was performed by ShineRoar probes analysis.Results People with GG genotype at position 196 in exon 6 of TNFR2 gene have more risks of development of CAD(OR=2.556,95% CI1.051～6.218, χ2=4.57,P=0.033)and CA(OR=2.547,95% CI1.162～5.579,χ2=5.81,P=0.016) than those with TT genotype.Further analysis after adjustment for sex and age demonstrated that GG genotype was not associated with CAD(OR=0.614,95% CI0.166～2.279,χ2=0.53,P=0.466)and coronary atherosclerosis(OR=O.644,95%CI0.200-2.069,χ2=0.55,P=0.459).Conclusion Tumor necrosis factor receptor 2 gene polymorphism at position 196 in exon 6 was not an independent risk factor of development of CAD and coronary atherosclerosis among Han Chinese.
