Genetic polymorphism has a vital role in the pathogenesis and development of myocardial infarction (MI). Single nucleotide at any one amino acid sequences can result diseased state. A single gene exhibit genetic more than position giving rise to different variants. angiotensinogen (AGT) M235T, AGT T174M, angiotensin-1-converting enzyme (ACE) I/D, endothelial nitric oxide synthase (eNOS), methyl...
