title: Platelet glycoprotein Ia 807C/T and 873G/A polymorphisms in patients with venous thromboembolism.
abstract: Two silent polymorphisms (807C/T and 873G/A) within glycoprotein Ia (GPIa) gene have been implicated in increased risk of developing thrombosis and myocardial infarction in affected individuals. The aim of this study was to investigate the GPIa gene polymorphism in patients with venous thromboembolism (VTE). A multiplexed allele specific-polymerase chain reaction (AS-PCR)-based method was used to determine the GPIa 807T/873A allele frequency in 77 patients with VTE and 106 healthy controls. The allelic frequency for 807T/873A was 33% in the patient group and 38% in the control group. The allelic frequency for 807C/873G was 66% in the patient group and 62% in the control group. The genotypic frequencies were 8% for 807TT/873AA, 42% for 807CC/GG, and 50% for 807CT/GA in the patient group. In the control group, the frequencies were 12% for 807TT/873AA, 35% for 807CC/873GG, and 52% for 807CT/873GA. As a result, the glycoprotein Ia 807C/T and 873G/A dimorphisms were not shown as risk factors for VTE.
