摘要

India being a country with vast diversity is expected to have different dietary and life style patterns which in turn may lead topopulation-specific environmental risk factors. Further, the interaction of these risk factors with the genetic makeup of pop-ulation makes it either susceptible or resistant to cardiovascular disease. One such candidate gene is angiotensin convertingenzyme (ACE) for various cardiovascular mechanisms. ACE is the key enzyme of the renin angiotensin aldosterone systempathway which maintains homeostasis blood pressure in the body and any variation in the levels is reported to be associatedwith various complex diseases. The DD genotype is found to increase ACE levels, which is associated with cardiovasculardiseases and decrease in ACE levels are associated with kidney diseases. The aim of this study was to understand the distribu-tion of ACE I/D polymorphism and ACE levels among Brahmins of National Capital Region (NCR) north India, with respectto age and sex ratio distribution. In this study, 136 subjects of which 50 males and 86 females, who were unrelated up to firstcousin, aged 25 to70 years were studied.ACEgene was found to be polymorphic with high frequency of heterozygote (ID)followed by II and DD genotypes. The studied population was found to be in Hardya€“Weinberg equilibrium with respect toACE I/D polymorphism (P=0.55). I allele frequency was found to be higher (0.560) than the D allele (0.44). The medianlevel of ACE was found to be 65.96 ng/mL (48.12a€“86.24) which is towards lower side of the normal range. ACE levels werefound to be increased among individual having either of the homozygotes that is II or DD and higher frequency of heterozy-gote (ID) is indicative of advantage in the population by maintaining lower ACE levels. The limitation of the present study islow sample size, however, the merit is that the subjects belonged to a Mendalian population with a common gene pool
