Background: The Renin-Angiotensin System (RAS) is an important regulator for blood pressure and kidney disease. The level of vaso active peptide Angiotensin-II is mainly determined by the RAS enzyme angiotensin converting enzyme-1 (ACE-1).Aim: To investigate the association of ACE I/D polymorphism and Chronic Kidney Disease (CKD) in south India.Methods: In the present study, we have collected CKD patients (n = 147) and control subjects (n = 211) from Tamilnadu. Genotyping was carried out by polymerase chain reaction (PCR) on the basis of allele specific primers.Results: The DD genotype is associated with the female population (OR-CI = 2.40 (1.05-5.51), p = 0.04) as compared to the male population (OR-CI = 0.75 (0.37-1.51), p = 0.42). Further, we found the over representation of ''I'' -allele (homozygous II and heterozygous ID) in unaffected males [OR (CI) -0.58 (0.32-1.04), p = 0.07] which suggests its protective role in male population.Conclusion: The DD genotype of ACE is associated with CKD in south India.Ó 2014 Production and hosting by Elsevier B.V. on behalf of Ain Shams University.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
