Clinical analysis of the polymorphism of clopidogrel and aspirin-related genes / 临床神经病学杂志

ABSTRACT

Objective To analyse the polymorphisms of CYP2C19,GPⅢa,PTGS1,GP1BA genes.Methods The basic information of 159 patients in the department of neurology of our hospital during January 2017 to November 2017 was collected. CYP2C19、GPⅢa、PTGS1、GP1BA genes were detected. Results The average age of the patients was (65.32 +12.71)years old,including 112 men (70.4%)and 47 female (29.6%). As for the CYP2C19*2G681Apolymorphism,there were 58 GG-genotype carriers,82 GA-genotype carriers and 19 AC-genotype carriers. For the CYP2C19*3G636Apolymorphism,there were 141 GG-genotype carriers and 18 GA-genotype carriers,for the CYP2C19*17C806Tpolymorphism,there were 155 CC-genotype carriers and 4 CT-genotype carriers. For the GPⅢa polymorphism,the TT genotype had 157 carriers,and the TC genotype had two carriers. For the PTGS1 polymorphism,there were 159 AA-genotype carriers.For the GP1BA polymorphism,the CC genotype had 136 carriers and the CT genotype had 23 carriers. The distribution of genotypes fitted the Hardy-Weinberg equilibrium for all the polymorphisms,except those of PTGS1.Phenotypesthere were 2 clopidogrel ultra metabolizer (1.3%),47 extensive metabolizer (29.6%),82 intermediate metabolizer (51.6%),and 28 poormetabolizer (17.6%). For aspirin,2 resistance (1.3%)and 157 sensitive (98.7%).Conclusion Clopidogrel poor metabolizer is significantly higher than aspirin resistance.
