Recently it was reported that Insertion/Deletion polymorphism in the gene coding for Angiotensin-Converting Enzyme (ACE) is associated with human capacity for physical performance. This study was performed to genotyping of the ACE gene to determine the correlation between elite endurance performance and ACE I/D gene polymorphism. DNA sample was obtained from peripheral blood, hair roots and mouth epithelial cell in 739 general population and 200 elite athletic performance students. The ACE gene was amplified by polymerase chain reaction (PCR) using allele specific oligonucleotide primers. 155, 525 bp and 237 bp PCR products indicating the presence of insertion(I) and deletion(D) alleles, respectively, were clearly resolved after electrophoresis on a 2% agarose gel with ethidium bromide. Of the 200 elite athletic performance population subjects, 68(34%) showed ACE genotype 11,100(50%) genotype ID and 32(16%) genotype DD. Of the 739 general population subjects, 259(35.1%) showed ACE genotype 11,363(49.1%) genotype ID and 117(15.8%) genotype DD. Therefore ACE I/D gene polymorphism was not associated with human capacity for physical performance.(p>0.05)

The angiotensin converting enzyme (ACE) is a key component of the renin-angiotensin system thought to be important in the pathogenesis of hypertension and cardiovascular diseases. Deletion polymorphism in the ACE gene may be a risk factor for myocardial infarction. The insertion/deletion (I/D) polymorphism of the ACE detected by PCR analysis appears to be associated with hypertension in Koreans and its nucleotide was subcloned into T-vector and its nucleotide sequences were determined. We also examined an association between hypertension and genetic variance of ACE. We identified the angiotensin I-converting enzyme genotype in 127 hypertensive and 189 normotensive Korean subjects. The distribution of ACE genotype II, ID, DD were 39.2%, 40.2%, 20.6% respectively and the frequency for ACE alleles I and D were 0.593 and 0.407, respectively in all subjects. The frequency of D allele in Korean males is higher than that of Korean females (male; 0.438 : female; 0.267), and the frequency of I allele in Korean females is higher than that of Korean males (female; 0.733 : male; 0.562). Genotype distributions of angiotensin I-converting enzyme genes in Korean normal adult population were different from that of Caucasians (P<0.001). There were no significant differences in genotype frequency between the hypertensive control group (n=127) and the normotensive group (n=189). We observed significant differences of ACE genotype distribution between the male group and the female group in total (P=0.001) and in hypertensive Korean subjects (P=0.013).

The polymorphism (insertion, I or deletion, D) of angiotensin converting enzyme (ACE) gene is designated as the presence of a 287 bp Alu repeat. The D/D homozygote carrier is associated with high ACE activity, and this high activity has been implicated with hypertension, coronary artery disease, or diabetic nephropathy. We studied the clinical candidate marker in ACE gene polymorphism using chemical and hematological analysis. The subjects are divided into normotensive and hypertensive groups and ACE genotype in the group was confirmed by PCR method. Chemical analysis was preceded with Hitachi7060, and hematological analysis was performed using Mythic 22. In 116 targeted people, 17 (38.64%) of 44 I/I genotype group are hypertension, 15 (34.09%) in 44 with D/I, but, D/D type in the 28 cases is 15 patients (53.57%) in hypertension. In hypertension group, biochemical analysis (triglyceride, and alkaline phosphatase) and hematological analysis (white blood cell, platelet) are showed high value in D/D genotype of ACE gene. The relationship between hypertension and ACE genotype is the same results as previously reported and we thought that the high laboratory value of white blood cell, platelet, triglycerides, and alkaline phosphatase are also indicator of hypertension in D/D type of ACE.

Sasang Constitutional Medicine focuses on the different constitutional manifestations of the individual's nature and emotions. The nature and emotions drive the ascending and descending of Qi in the body. And this dynamics of the Qi's ascent and descent shapes the different types of structures, functions and temperaments. Although Sasang Constitutional Medicine has many advantages, its diagnosis of the constitution still depends on the doctors' own idea and has no objective identification. So many doctors in Korea have been trying to solve this problem. Recently, there are several efforts to find out the relationship between genetic information and constitution. By the way, May, 1998 there is a astonishing report about the gene which determines the human performance, that is ACE(angiotensin converting enzyme). And it suggests that the I allele was associated with improved endurance performance. ACE has three genotype including II, ID and DD. "I" means insertion and "D" means deletion. We determined the type of the Sasang constitution with QSCCII questionaire and the one's ACE genotype with PCR of the 127 people and we discovered the relationship between the constitution and the ACE genotype. The result is as follow. Among 39 people who have the II genotype, 7(18%) belong to Taeum(Taiyin), 9(23.1%) belong to Soyang(Shaoyang) and 23(59%) belong to Soeum(Shaoyin). Among 62 people who have the ID genotype, 18(29%) belong to Taeum(Taiyin), 21(33.9%) belong to Soyang(Shaoyang) and 23(37.1%) belong to Soeum(Shaoyin). Among 26 people who have DD genotype, 11(42.3%) belong to Taeum(Taiyin), 4(15.4%) belong to Soyang(Shaoyang) and 11(42.3%) belong to Soeum(Shaoyin). This data indicates that there are implicable relationship between the Sasang constitution and ACE genotype. Especially people who have II genotype have much possibility to be a Soeum(Shaoyin) person (59%) and Soyang(Shaoyang) person have less possibility to have DD genotype (15.4%). With this conclusion, we suggest further study of relationship between the Sasang constitution and ACE genotype and we think that other polymorphism can be a candidate of the partner of Sasang constitution.

Angiotensin converting enzyme (ACE) is a vital enzyme in the renin-angiotensin-aldosterone system, and there are literature reports describing its relationship between the ACE polymorphism and muscular strength, muscular endurance and flexibility. The purpose of this study is to identify the distribution of the ACE gene polymorphism among individual golfers and the relationship between different golfers group. We analyzed the ACE gene polymorphism to study the individual differences among professional golfers (n=35), junior golfers (n=30) and general golfers (n=25). Genotype frequencies of DD, ID and II in total golfers (n=90) were 16.7%, 52.2% and 31.1% respectively. In professional golfers, the frequencies of DD, ID and II were 25.7%, 45.7% and 28.6% respectively. The frequency of DD genotype in professional golfers was higher than in junior golfers and in general golfers, but the II genotype in professional golfers was lower than in other groups. In conclusion, these data suggest that the capability and power of golf exercise are associated with the hereditary characteristics of the ACE polymorphism.

이 연구는 한국인에서 적용할 수 있는 근력관련 유전적 소인을 ACE 유전자와 ACTN3 유전자를 단일유전자 수준과 다중유전자 수준에서 관계성을 규명하는데 목적이 있다. 연구의 목적을 위해 근력운동종목의 엘리트선수 158명, 국가대표선수 106명, 대조군 676명을 동원하여 ACE ID 다형성과 ACTN3 R577X 다형성 분포를 분석했다. 연구결과, ACE 다형성에서 II 유전형 및 I 대립형질은 유의하게 높은 분포를 가졌고, 반면 DD 유전형 및 I 대립형 질은 유의하게 낮은 분포를 가졌다(Top-Class vs. Control: 41.4% vs. 32.1 for II genotype, 67.1% vs. 57.7% for I allele, p<0.05). ACTN3 다형성에서 RR 유전형 및 R 대립형질은 유의하게 높았고 XX 유전형 및 R 대립형질은 유의하게 낮았다(Top-Class vs. Control: 42.3% vs. 29.0 for RR genotype, 65.3% vs. 54.8% for R allele, p<0.05). 다중유전자 수준에서 근력은 ACE 다형성과 ACTN3 다형성이 조합된 우성조합유전형(II/ID+RR/RX)이 최우수 경기력에서 유의하게 높은 분포를 가졌다(Top-Class vs. Control: 82.9% vs. 66.7% for II/ID+RR/RX, p<0.05). 또한 최우수 경기력을 가진 국가대표는 엘리트와 대조군 보다 유의하게 높은 TGS를 가졌다($66{\pm}0.9$ vs. $58{\pm}1.9$ vs. $56{\pm}2.3$, p<0.05). 이를 근거로 우성조합유전형이 최우수 근력 경기력을 가질 가능성에 대한 승산비는 2.43배(CI:1.45-4.09, p<0.001)였다. 따라서 ACE 다형성과 ACTN3 다형성은 한국인에서 근력과 관계된 유전형으로 확인되었으며, 두 유전자는 상호 조합된 다중유전형에서 근력 경기력에 영향을 줄 것으로 사료된다. 또한 ACE 다형성과 ACTN3 다형성을 조합한 다중유전자는 근력 경기력을 예측할 수 있은 유전적 요인으로 사료되었다.

Genetic factors are important in the pathogenesis of coronary artery disease (CAD). Angiotensin converting enzyme (ACE) gene insertion(I)/deletion(D) polymorphism is one of the genetic factor found to be related with CAD. We investigated the association between I/D polymorphism of the ACE gene and the presence of CAD. Threehundred and seven patients (187 males and 120 females, aged between 35-80, mean $54.3{\pm}9.8$ years) who underwent diagnostic coronary angiography were included in the study. ACE I/D polymorphism was detected by polymerase chain reaction. Of the 307, 176 had CAD. The most frequently observed genotype in all subjects was ID (47.9 %). However, in patients with CAD the frequency of II genotype was lower whereas DD genotype was higher compared to the controls (p < 0.05). The number of D allele carrying subjects were also higher (p < 0.05) in CAD patients. The logistic regression analysis indicated that the ACE D allele is an independent risk factor (odds ratio = 1.48, 95% CI = 1.01-2.18, p < 0.05). In conclusion, the I/D polymorphism of ACE gene (carrying D allele) is an independent risk factor for CAD in the studied Turkish population.

Previously, we made a study report on the genotype distribution and the gene frequency of angiotesin I-converting enzyme (ACE) in Korean population, and on the association between hypertension and genetic variance of ACE. This time, we have investigated a rapid mismatch-PCR/RFLP assays for the variant of the angiotesin II type 1 receptor ($AT_1R$) gene (an $A{\rightarrow}C$ transversion at position 1166 of $AT_1R$ gene), a mutation which may interact with the ACE polymorphism in the determining of risk of myocardial infarction. The genotype distributions of Koreans' angiotensin II type 1 receptor gene were AA (66.3%):AC (28.1%):CC (5.6%), thus the AA genotype was most numerous, and the allele frequency was A:C = 0.803:0.197. Genotype distributions were shown as AA (76.8%):AC (20.9%):CC (2.3%), the allele frequency was A:C = 0.872:0.128 in the male group, and AA (47.4%):AC (41.0%):CC (11.6%), A:C = 0.679:0.321 in the female group. Differences were highly significant between the male and female groups (p<0.0001). Genotype distributions between angiotensin II type 1 receptor gene and angiotensin converting enzyme gene showed that there is no significance between $AT_1R$ genotypes and ACE genotypes in total subjects (p>0.05).

The genetic factors that contribute to the development of coronary artery disease (CAD) are poorly understood. It is likely that multiple genes that act independently or synergistically contribute to the development of CAD and the outcome. Recently, an insertion/deletion (I/D) polymorphism of the human angiotensin I-converting enzyme (ACE) gene, a major component of the renin-angiotensin system (RAS), was identified. The association of the ACE gene D allele with essential hypertension and CAD has been reported in the African-American, Chinese, and Japanese populations. However, other studies have failed to detect such an association. It has been suggested that these inconsistencies may be due to the difference in backgrounds of the population characteristics. In the present study, we investigated the I/D polymorphism of the ACE gene in 103 subjects of both sexes, consisting of 59 normal controls and 44 patients with hypertension. The allele and genotype frequency were significantly different between the hypertensive and control groups (p < 0.01). Among the three ACE I/D variants, the DD genotype was associated with the highest value of the mean systolic blood pressure [SBP] and mean diastolic blood pressure [DBP] (p = < 0.05) in men, but not in women. In the overall population, the mean SBP and DBP was highest in DD subjects, intermediate in I/D subjects, and the least in II subjects.
