Genetic variations in CYP2C19 are known to influence individual drug responses. Here, differences in CYP2C19 alleles, genotypes, and phenotypes in patients with cardiovascular disease from the Yunnan-Guizhou Plateau were systematically surveyed to provide a reference for appropriate treatment approaches.Methods: The CYP2C19*2, *3, and *17 variants were determined by RT-qPCR in 1934 patients with cardiovascular disease from 10 different areas of the Yunnan-Guizhou Plateau. Clinical data were analyzed using χ2 tests.Results: The proportions of the CYP2C19*1, *2, *3, and *17 alleles in the study cohort were 64.94, 29.81, 4.42, and 0.83%, respectively, while the frequencies of nine observed genotypes (*1/*17, *1/*1, *2/*17, *3/*17, *1/*2, *1/*3, *2/*2, *2/*3, *3/*3) were 1.03, 42.09, 0.57, 0.05, 38.73, 5.95, 8.89, 2.53, and 0.16%, respectively. Four metabolic phenotypes were found in the population, namely, rapid (1.03%), normal (42.09%), intermediate (45.29%), and poor (11.58%) metabolizers. Regional differences in allele and phenotype distribution were observed.Conclusion: These results represent the first comprehensive profile of CYP2C19 variants in patients with cardiovascular disease from the Yunnan-Guizhou Plateau, offering a valuable genetic reference for the selection of optimal treatment strategies.Keywords: plateau, clopidogrel, CYP2C19, allele, genotype, phenotype |
