How common is PAI-1 4G 4G?
TABLE 2. PAI-1 Genotypes and PAI-1 Allele Frequencies in Stroke Cases and Controls
| Study A | Study B | |

What is PAI-1 deficiency?
Complete plasminogen activator inhibitor 1 deficiency (complete PAI-1 deficiency) is a disorder that causes abnormal bleeding. In people with this disorder, bleeding associated with injury can be excessive and last longer than usual.
What is plasminogen inhibitor PAI-1 4G 5G?
Background and Purpose— Plasminogen activator inhibitor type 1 (PAI-1) is the main inhibitor of fibrinolysis, and high levels may increase the risk of cardiovascular disease. The 4G/5G polymorphism affects PAI-1 gene transcription with lower levels of plasma PAI-1 in the presence of the 5G allele.
What is pai1 test?
Plasminogen activator inhibitor-1 (PAI-1) testing is indicated for unexplained mild-to-moderate delayed bleeding disorders, typically associated with trauma or surgery. Normal findings : Antigen assay: 2-46 ng/mL.
What is PAI polymorphism?
The PAI-1 4G/5G polymorphism is a DNA sequence variation that plays a key role in regulating PAI-1 gene expression. Studies have shown that the PAI-1 activity of the 4G allele promoter is higher than that of the 5G allele promoter in a cytokine-stimulated state.
What is PAI-1 4G 5G mutation?
What is PAI 4G 5G?
The 4G/5G polymorphism is a common polymorphism in the promoter region of the PAI-1 gene. 10. Both the 4G and 5G alleles have a binding site for an activator of transcription. The 5G allele, however, has an additional binding site for a repressor, resulting in lower transcription rates and less PAI-1 activity.
