Eleven loci with new reproducible genetic associations with allergic disease risk

A recent genome-wide association study (GWAS) identified 99 loci that contain genetic risk variants shared between asthma, hay fever and eczema. Many more risk loci shared between these common allergic diseases remain to be discovered, which could point to new therapeutic opportunities. To identify novel risk loci shared between asthma, hay fever and eczema by applying a gene-based test of association to results from a published GWAS that included data from 360,838 individuals. We used approximate conditional analysis to adjust the results from the published GWAS for the effects of the top risk variants identified in that study. We then analysed the adjusted GWAS results with the EUGENE gene-based approach, which combines evidence for association with disease risk across regulatory variants identified in different tissues. Novel gene-based associations were followed up in an independent sample of 233,898 individuals from the UK Biobank study. Of the 19,432 genes tested, 30 had a significant gene-based association at a Bonferroni-corrected P-value of 2.5×10-6. Of these, 20 were also significantly associated (P
