摘要：Background: A significant role of Renin-angiotensin system (RAS) genetic variants in the pathogenesis of essential hypertension and cardiovascular diseases has been proved. This study aimed to develop a new, fast and cheap method for the simultaneous detection of two missense single nucleotide polymorphisms (T207M or rs4762 and M268T orrs699) of angiotensinogen (AGT) in single-step Multiplex Hexa-Primer Amplification Refractory Mutation System - polymerase chain reaction (H-ARMS-PCR).Methods: In this case-control study, 148 patients with coronary artery disease (CAD) and 135 controls were included. The patients were referred to cardiac centers in Afshar Hospital (Yazd, Iran) from 2012 to 2015. Two sets of inner primer (for each SNP) and one set outer primer pairs were designed for genotyping of rs4762 and rs699 in single tube H-ARMS-PCR. Direct sequencing of all samples was also performed to assess the accuracy of this method. DNA sequencing method validated the results of single tube H-ARMS-PCR.Results: We found full accordance for genotype adscription by sequencing method. The frequency of the AGT T521 and C702 alleles was significantly higher in CAD patients than in the control group (OR: 0.551, 95% CI: 0.359-0.846, P=0.008 and OR: 0.629, 95% CI: 0.422-0.936, P=0.028, respectively).Conclusion: This is the first work describing a rapid, low-cost, high-throughput simultaneous detection of rs4762 and rs699 polymorphisms in AGT gene, used in large clinical studies.
