Association of angiotensin-converting enzyme gene variations with coronary artery disease in the Iranian population.

Background: The purpose of this study was to identify the angiotensin-converting enzyme (ACE) gene (I/D) variations in CAD patients and healthy controls in an Iranian population (West Azerbaijan province of Iran).

Method: This cross-sectional study included 95 CAD patients and 203 healthy controls. ACE I/D polymorphisms were assessed using PCR, and their frequency was determined.

Association of MMP-1 (rs1799750)-1607 2G/2G and MMP-3 (rs3025058)-1612 6A/6A Genotypes With Coronary Artery Disease Risk Among Iranian Turks.

The study was conducted to evaluate the association between MMP-1 (rs1799750)-1607 1G/2G and MMP-3 (rs3025058)-1612 5A/6A polymorphisms/haplotypes and coronary artery disease (CAD) risk among Iranian Turks. Totally, 102 patients with CAD and 102 healthy subjects joined the study. Genomic DNA isolation was carried out using "salting out" method from 3 to 4 mL of whole blood samples.
