Three CpG sites were significantly associated (FDR < 0.05) with asthma at age 4: cg22971191 in SLC10A2 (solute carrier family 10 (sodium/bile acid cotransporter) member 2), cg18515031 in C10orf104 (chromosome 10 open reading frame 104) and cg05712073 in ZNF384 (Zinc Finger Protein 384). Here, SLC10A2 is linked to asthma.
