Notes: 

Clinical Indications: The 4G allele of a recently described common guanine insertion/deletion polymorphism (4G/5G) in the PAI-1 gene promoter region is associated with higher plasma plasminogen activator inhibitor (PAI-1) activity. When PAI-1 is high, fibrinolytic activity is depressed, and there is increased risk for arterial and venous thrombosis. PAI-1 is also a significant risk factor for coronary artery disease, myocardial infarction and recurrent spontaneous abortion.
