In this article, the ADE and I/D polymorphism information is collected. ADE turns anjiotensin I into anjiotensin II, a strong vasoconstrictor, and reduces the effectiveness of bradicine. ADE genes are expressed in the human chromosome 17 in three genotypes in the intron 16. These genotypes are allels I and D, which are called "insertion" and "deletion". D alelium is associated with an increased risk of developing many pathological conditions, such as coronary heart disease and ventricular hypertrophy. Homozigot people with D allies have a bad prognosis in many heart cases. It is associated with an increase in the performance of the athletes. Keywords: Angiotensin Converter Enzyme, ADE I/D polymorphism, cardiovascular diseases Abstract Angiotensin Converting Enzyme and I/D Polymorphism The renin-angiotensin system plays a role in the pathogenesis of cardiovascular diseases and the effectiveness of angiotensin Converter Enzyme (ACE) inhibitors in the treatment of hypertension and heart failure emphasizes the prominent role of ACE in the cardiovascular system. This review aims to discuss angiotensin converting enzyme and I/D polymorphism. ACE converts angiotensin I to the potent vasoconstrictor angiotensin II and that degrades bradykin. ACE gene is located on human chromosome 17 expressing three genotypes within the intron 16 of the related gene structure. These genotypes are classified as I and D alleles which are referred to as insertion and deletion, respectively. The D allele has been associated with an increased risk of developing several pathological processes, such as coronary heart disease and ventricular hypertrophy. Several heart conditions appear to have a worse prognosis in subjects homozygous for the D allele, whereas the I allele has been associated with enhanced endurance performance in sportsmen. Key words: Angiotensin converting enzyme, ACE I/D polymorphism, cardiovascular diseases
