TSLP and asthma: This may be evidenced by the fact that only a single meQTL colocalized with a GWAS SNP at the TSLP locus in the TAGC GWAS, while the same SNP, rs1837253, colocalized with three meQTLs, including two additional CpGs, in the childhood and adult onset asthma (Additional file 1: Fig. S7), representing potential contributors to asthma disease mechanisms that were missed in the TAGC GWAS.
