Multiancestry association study identifies new asthma risk loci that colocalize with immune-cell enhancer marks

Florence Demenais et al. Nat Genet. 2018 Jan.

Abstract

We examined common variation in asthma risk by conducting a meta-analysis of worldwide asthma genome-wide association studies (23,948 asthma cases, 118,538 controls) of individuals from ethnically diverse populations. We identified five new asthma loci, found two new associations at two known asthma loci, established asthma associations at two loci previously implicated in the comorbidity of asthma plus hay fever, and confirmed nine known loci. Investigation of pleiotropy showed large overlaps in genetic variants with autoimmune and inflammatory diseases. The enrichment in enhancer marks at asthma risk loci, especially in immune cells, suggested a major role of these loci in the regulation of immunologically related mechanisms.

Figure 1
Manhattan plots of the results of European-ancestry and multi-ancestry random-effects meta-analyses of asthma risk. (a) The European-ancestry meta-analysis pertains to 19,954 cases and 107,715 controls. (b) The multi-ancestry meta-analysis pertains to 23,948 cases and 118,538 controls. Each locus is annotated by its cytogenetic band location. The × axis represents chromosomal location and the y axis represents −log10 (P value) for tests of association between SNPs and asthma. Black, previously known loci; red, new loci identified in the European-ancestry meta-analysis; blue, additional new loci identified in the multi-ancestry meta-analysis The dashed horizontal line denotes P=5×10−8.

Figure 2
GRAIL circle plot of connectivity between genes at asthma risk loci. The 17 asthma risk loci are along the outer ring (the 10p14 locus was ignored because it corresponds to a gene desert); the internal ring represents the genes at these loci. The width of the lines drawn between genes corresponds to the strength of the literature-based connectivity, with thicker lines representing stronger connections.
