One significant DMP (differentially methylated position) (α = 0.05/742,442) was detected in the NTR asthma EPIC dataset (cg26272069, GABBR1 gene), and 95 significant DMPs were detected in the NTR biobank 450k dataset (α = 0.05/411,169) (Supplementary Tables S2 and S3). Here, GABBR1 is linked to asthma.
