Association between polymorphisms of platelet membrane glycoprotein Ibα and risk of coronary heart disease in Han Chinese, Henan, China.
2015
Objective: To study the relationship between human platelet alloantigens-2 (HPA-2) polymorphism, Kozak sequence polymorphism, macroglycopeptide region variable number of tandem repeats (VNTR) polymorphism of GPIbα and coronary heart disease (CHD). Methods: In the present study, blood obtained from 403 patients with CHD and 500 healthy controls was detected by PCR or PCR-RFLP methods to analyze the genotypes of HPA-2, Kozak sequence and VNTR. Results: About HPA-2 polymorphism, there were significant differences between CHD group and control group in TM+MM genotype (13.15% vs. 8.60%, P 0.05). Conclusions: The M allele of HPA-2 could be an important risk factor for CHD; the CC genotype of Kozak sequence would be a biomarker of genetic susceptibility about CHD; and each genotype of VNTR is no associated with CHD. No significant differences between control group and CHD group about haplotypes of these genes.
