阿司匹林抗血小板相关基因多态性在汉族NSTEMI患者人群中的分布OACSTPCD

Objective:To analyze the genotype and allele distribution characteristics of GPⅢa PLA2(rs5918),PEAR1(rs12041331),and PTGS1(rs10306114)genes related to the antiplatelet pharmacological effects of aspirin,providing reference for individualized treatment of Chinese Han NSTEMI patients.Methods:A total of 107 Han patients with NSTEMI in Beijing Luhe Hospital affiliated to Capital Medical University from January 2016 to December 2022 were selected as the research subjects.The genotypes of GPⅢa PLA2(rs5918),PEAR1(rs12041331)and PTGS1(rs10306114)were detected by fluorescence stain-ing in situ hybridization.The frequency distribution and allele distribution of genotype were analyzed.The results were analyzed whether there were statistical differences in the distribution of related alleles between the Han NSTEMI population and some popu-lations in the 1000 Genomes database.Results:In the Han NSTEMI population,the genotype frequencies of GPⅢa PLA2(rs5918)locus were TT 97.20%,TC 2.80%and CC 0%,the allele frequencies were T 98.60%and C 1.40%.The genotype frequencies of PEAR1(rs12041331)locus were GG 42.06%,GA 44.86%and AA 13.08%,the allele frequencies were G 64.49%and A 35.51%.The genotypes at the PTGS1(rs10306114)locus were all AA(100%),no AG or GG genotype was found.Conclusion:In the NSTEMI population of Han ethnic group,the mutation at GPⅢa PLA2(rs5918)site related to aspirin antiplatelet pharmacology is rare,and there is no mutation at PTGS1(rs10306114)site.Wild homozygotes are dominant in these two gene loci,while mutations in PEAR1(rs12041331)are more common.Some of the findings in this study are similar to those in previous reports or other populations included in the relevant database;however,some results differ from previous reports or other populations.
