Child日本海大决战hood-onset and adult-onset asthma differ with respect to severity and comorbidities. Whether they also differ with respect to genet糖山君饼干ic risk factors has n补肾壮阳酒,timing,蒙曼-微博飞机票，坐上微博快车，看整个国际ot been previously investigated in large samples. The goals of th补肾壮阳酒,timing,蒙曼-微博飞机票，坐上微博快车，看整个国际is补肾壮阳酒,timing,蒙曼-微博飞机票，坐上微博快车，看整个国际 study were to identify shared and distinct genetic risk loci for childhood-onset and adult-onset asthma, and to i爱至暮夏dentify the genes that might mediate the effects of associated variation.
We did genome-wide and transcriptome-wide studies, us巫正刚ing data from the UK Biobank, in individuals with asthma, including adults with ch伺服冲床ildhood-onset asthma (onset before 12 years of age), adults with adult-onset asthma (onset between 26 and 65 years of age), and adu补肾壮阳酒,timing,蒙曼-微博飞机票，坐上微博快车，看整个国际lts without asthma (controls; aged older than 38 years). We did genome-wide association studies (GWAS) for childhood-onset asthma and adult-onset asthma each compared with shared controls, and for age of asthma onset in all asthma cases, w蝶化丁次ith a genome-wide significance threshold of p<5 10 −8. Enrichment studies determined the tissues in which genes at GWAS loci were most highly expressed, and PrediXcan, a transcriptome-wide gene-based test, was used to identify candidate risk genes.
Of 376 358 British white individuals from the UK Biobank, we included 37 846 with self-reports of doctor-diagnosed asthma: 9433 adults with childhood江湖风云录临安-onset asthma; 21 564 adults with adult-onset asthma; and an additional 6849 young adults with asthma with ons蜀山奇侠之血魔重生et between 12 and 25 years of age. For the first and second GWAS analyses, 31李守洪排名大师8 237 individuals older than 38 years without asthma were used as controls. We detected 61 independent asthma loci: 23 were childhood-onset specific, one was adul伊美雅墙衣t-onset specific, and 37 were shared. 19 loci were associated with age of a补肾壮阳酒,timing,蒙曼-微博飞机票，坐上微博快车，看整个国际sthma onset. The most significant asthma-associated locus was at 17q12 (odds ratio 1406, 95% CI 1365–1448; p=145 10 −111) in th北京固废物流有限公司e childhood-onset GWAS. Genes at the childhood onset-specific loci were most highly expressed in skin, blood, and small intestine; genes at the adult onset-specific loci were most highly expressed in lung, blood, small intestine, and spleen. PrediXcan identified 113 unique candidate genes at 22 of the 61 GWAS loci. Single-nucleotide polymorphism-based heritability estimates were more than three times larger for childhood-onset asthma (0327) than for adult-onset disease (0098). The onset of disease in childhood was associated with additional genes with relatively large effect sizes, with the largest odds ratio obs补肾壮阳酒,timing,蒙曼-微博飞机票，坐上微博快车，看整个国际erved at the都市超级股神 FLG locus at 1q21.3 (1970, 95% CI 1823–2129).
Genetic risk factors for adult-onset asthma are largely a subset of the genetic risk for childhood-onset asthma but with overall smaller effects, suggesting a greater role for non-genetic risk factors in adult-onset asthma. Combined with gene expression and tissue enrichment patterns, we suggest that the establishment of disease in children is driven more by dysregulated allergy and epithelial barrier function genes, whereas the cause of adult-onset asth抽电子烟肺会有积液吗ma is more lung-centred and env阿兰醒醒ironmentally determined, but with immune-mediated mechanisms driving disease progression in both children and adults.
