Platelet glycoprotein polymorphisms as risk factors for thrombosis
1Department of Medicine, Baylor College of Medicine, Houston, Texas 77030, USA.
Genetic platelet polymorphisms, like GPIIIa PIA2, are linked to increased arterial disease risk. These genetic factors, particularly in younger individuals and women, contribute to thrombosis and should be recognized as key risk factors.
Area of Science:
- Cardiovascular Genetics
- Hematology
- Thrombosis Research
Background:
- Acute ischemic arterial diseases involve both blood platelets and genetic factors.
- Platelet glycoprotein polymorphisms are increasingly recognized as potential contributors to thrombotic events.
Purpose of the Study:
- To review the role of various platelet glycoprotein gene polymorphisms in the development of acute ischemic arterial diseases.
- To assess the association between specific polymorphisms and increased risk for arterial thrombosis.
Main Methods:
- Analysis of clinical association studies examining platelet glycoprotein gene variants.
- Review of investigations on the prothrombotic potential of identified polymorphisms in platelets and cell lines.
Main Results:
- The GPIIIa PIA2 polymorphism is associated with a modest increased risk for coronary artery disease events and exhibits a prothrombotic phenotype.
- Support exists for platelet GPla (integrin alpha2) 807 T/C and GPIbalpha met145 and VNTR B/C genotypes as risk factors in younger populations.
- Other polymorphisms (GPIIb, FcgammaRIIa, P-selectin, alpha2 adrenergic receptor, TGF-beta) are suggested as risk factors or prothrombotic agents.
Conclusions:
- Platelet glycoprotein polymorphisms represent a significant category of genetic risk factors for arterial thrombosis.
- These genetic factors are particularly relevant for younger patients and women, warranting further investigation and clinical consideration.

Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
