rs1799983 (also known as Glu298Asp, E298D, or G894T) located in the NOS3 gene was associated with an ~2x risk (p=0.006) of developing pre-eclampsia (pregnancy-induced hypertension) and further complications of it in a study of ~50 African women.[PMID 16059745]

A large meta-analysis combining 26 studies (9,867 patients) found that homozygosity for rs1799983(T;T) increases risk of ischemic heart disease. The odds ratio was 1.31 (CI: 1.13-1.51).[PMID 15007011]

However, a study of 1,600 Greek patients concluded that rs1799983 was not associated with risk of acute myocardial infarction in that population.[PMID 18495009OA-icon.png]
