Background: Diabetic nephropathy (DN) is a leading cause of diabetes-related morbidity and mortality. The aim of this study was to evaluate the relationship of AGT M235T and apoprotein E (APO E) gene polymorphism with DN in Turkish patients of Type 2 diabetes, and to compare genotype and allele distributions among DN patients, non-DN patients, and healthy controls.
Methods: AGT M235T and APO E genotype and allele analysis were performed in 111 DN patients, 108 non-DN patients, 106 healthy control subjects for APO E genotype, and 100 for AGT M235T genotype polymorphism. APO E and AGT M235T genotype were determined by RFLP-PCR.
Results: The frequencies of APO E ε2/3, ε 3/3, ε 3/4 genotypes were 22.7%, 60%, 60%, respectively, among DN patients and 6.6%, 80%, 10.4%, respectively (p < 0.001), in the non-DN patients. The frequencies of AGT M235T MM, MT, TT genotypes among the same groups were 17%, 46%, 37% and 21%, 63%, 16%, respectively (p < 0.02). Having the ε2/3 genotype and TT genotype increased the risk for DN nephropathy [4.8-fold (95% CI: 1.94-11.67), 2.9-fold (95% CI: 1.27-6.69), respectively].
Conclusion: Our study has shown that AGT M235T TT genotype and APO E ε 2/3 genotype may be linked to a risk for DN among Turkish population.

Relationship between the AGT M235T genetic variant and the characteristics and prognosis of coronary atherosclerosis in patients with acute myocardial infarction.
Mol Biol Rep

Department of Internal Medicine, University of Medicine and Pharmacy at Ho Chi Minh City, 217 Hong Bang, District 5, Ho Chi Minh City, 700000, Vietnam.
Article Synopsis
- Genetic factors, notably the AGT M235T variant, were studied in relation to acute myocardial infarction (AMI) among 504 Vietnamese patients, aiming to analyze their impact on coronary atherosclerosis and 12-month mortality rates.
- The study found that the majority of patients had the TT genotype, and there were no significant differences in coronary artery conditions or mortality between different genotype groups.
- The conclusion indicated that the AGT M235T variant showed no association with atherosclerosis or mortality within the 12-month follow-up, suggesting a need for larger studies to confirm these findings.
Genetic Polymorphisms and Genetic Risk Scores Contribute to the Risk of Coronary Artery Disease (CAD) in a North Indian Population.

Article Synopsis
- - Coronary artery disease (CAD) is a major health issue in India, and this study looked at ten genetic polymorphisms affecting oxidative stress, blood pressure, and lipid metabolism in the Jat Sikh population to understand their link to CAD risk.
- - The research found that seven of these polymorphisms, specifically M235T, T174M, and A1166C, showed significant associations with increased CAD risk, with some haplotypes linked to higher risk even when accounting for other factors.
- - A higher polygenic risk score indicated a nearly double risk of developing CAD, highlighting important genetic factors for potential clinical and public health strategies in preventing and managing coronary artery disease.
The Association of M235T Genetic Polymorphism in Gene and Other Non-Genetic Factors with Essential Hypertension among Jordanian Patients.

Department of Pharmacology, School of Medicine, The University of Jordan, Amman 11942, Jordan.
Background: Hypertension, characterized by elevated pressure, poses a significant health risk. Recent studies in Jordan highlight high hypertension rates, emphasizing the need for genetic investigations to comprehend essential hypertension determinants. The gene, part of the Renin Angiotensin System, is linked to blood pressure regulation.

Article Synopsis
- A study investigated the link between specific genetic polymorphisms and ST elevation Myocardial Infarction in young Mexican individuals, involving 350 patients under 45 and 350 matched controls.
- The A1166C polymorphism was found to significantly increase the risk of Myocardial Infarction, while G20210A, G1691A, 97G > T, and A1298C did not show a similar association.
- Other factors like dyslipidemia, hypertension, smoking, and family history were also linked to increased risks, indicating that genetic variations might contribute to early cardiovascular issues, but more research is needed on gene interactions.
Impact of the gene polymorphisms in the renin-angiotensin system on cardiomyopathy risk: A meta-analysis.

Due to the inconsistent findings from various studies, the role of gene polymorphisms in the renin-angiotensin system in influencing the development of cardiomyopathy remains unclear. In this study, we conducted a systematic review and meta-analysis to summarize the findings regarding the impact of angiotensin converting enzyme (ACE) I/D, angiotensinogen (AGT) M235T, and angiotensin II Type 1 receptor (AGTR1) A1166C gene polymorphisms in patients with cardiomyopathy. We performed a comprehensive search of several electronic databases, including PubMed, Embase, the Cochrane Library, and Web of Science, covering articles published from the time of database creation to April 17, 2023.
