Association between matrix metalloproteinase-9 rs3918242 polymorphism and development of coronary artery disease in a Chinese population
We conducted a case-control study to investigate the role of one single nucleotide polymorphism of MMP-9 rs3918242 in the development of coronary artery disease. The rs3918242 was amplified with 435-bp DNA fragments using polymerase chain reaction coupled with restriction fragment length polymorphism.
