摘　　要： 哮喘是一种由遗传和环境因素共同影响的常见的气道慢性炎性疾病,其分子遗传学基础复杂多样,目前临床上仍无疗效显著的治疗方法.全基因组相关联研究通过寻找哮喘发病机制的基因靶点,从分子遗传学角度为儿童哮喘的精准化医疗提供新思路.现研究证明17q21位点上血清类黏蛋白1样蛋白3基因(ORMDL3)和gasdermin B (GSMDB)基因的表达影响儿童哮喘的易患性、严重性、及种族特异性.该文对17q21染色体位点上与儿童哮喘相关的基因进行综述. Asthma,a chronic inflammatory airway disease,is influenced by both genetic and environmental factors.It is a complex disease that involves the interplay among multiple physiological processes.Currently,it has been identified that 17q21 loci genes especially orosomucoid like 3 (ORMDL3) and gasdermin B (GSMDB) are strongly linked with the susceptibility and severity of childhood asthma by using of the Genome-Wide Association Study (GWAS).Furthermore,a better understanding of the molecular mechanism contributes to the asthma target therapeutics and precision medicine.This review summarizes the 17q21 loci genes associated with the susceptibility,severity,and race specificities of childhood asthma.
