阿司匹林代谢相关基因PEAR1的多态性在河南人群中的分布研究

Distribution of polymorphism of aspirin-metabolic gene PEAR1 in Henan population

目的研究河南地区人群中阿司匹林代谢相关基因血小板内皮聚集受体1(PEAR1)多态性的分布情况。方法采用荧光染色原位杂交检测法对2019年1月至12月来南阳医学高等专科学校第一附属医院体检的115名健康体检者的PEAR1(rs12041331)基因型进行检测。115名健康体检者中,男性69名,女性46名,年龄(40.0±3.5)岁。结果共发现PEAR1有3种基因型,即AA、GA和GG型,每种基因型的分布频率分别为12.17%(14/115)、46.09%(53/115)和41.74%(48/115)。将试验结果进行Hardy-Weinberg定律的吻合度测验,通过计算检测符合Hardy-Weinberg平衡定律(χ^(2)=1.24,P=0.362)。结论河南地区人群中PEAR1具有基因多态性,其中GA型为较常见的基因型。

Objective To study the distribution of polymorphism of aspirin-metabolic gene platelet endothelial aggregation receptor-1(PEAR1)in Henan population.Methods The PEAR1(rs12041331)genotypes of 115 healthy examinees taking physical examination at First Hospital Affiliated to Nanyang Medical College from January to December,2019,including 69 males and 46 females who were(40.0±3.5)years old,were determined by the polymerase chain reaction-restriction fragment length polymorphism method.Results Three PEAR1 genotypes were found,including AA,GA,and GG;and their distribution frequencies were 12.17%(48/115),46.09%(53/115),and 41.74%(48/115).The results'coincidence was tested according to the Hardy-Weinberg equilibrium law,and conformed to the law(χ^(2)=1.24,P=0.362).Conclusion There is PEAR1 polymorphism in Henan population,with GA as the common genotype.
