rs1799889 is an insertion/deletion polymorphism in the promoter region of the SERPINE1 gene, which is also known as plasminogen activator inhibitor type 1 (or PAI1 or PAI-1). [There are several entries in dbSNP covering this same position; the one here in SNPedia is the one with population frequency.] The most common allele has a run of 5 G's in the area around this SNP, and in the literature the allele is commonly called the 5G allele. A deletion of one nucleotide leads to the "4G" allele, i.e. rs1799889(-).
The 4G allele has been reported to increase risk for atherosclerosis and coronary artery disease [PMID 9484978]; on the other hand, the 5G allele may increase the risk of abdominal aortic aneurysm (AAA). [PMID 10805895]
In combination with the A2 allele of the ITGB3 gene, rs5918, the increased risk of myocardial infarction in a Finnish study population was 4 fold higher (odds ratio = 4.5, p=0.001), particularly in males (odds ratio = 6.4, p=0.0005) [PMID 9700201].
