We identified the following SNPs as the ones showing independent nominal associations: rs1800925 (−1112 C/T) in IL13–IL4 (only for atopic asthma), rs2071590 in LTA-TNF (only for asthma), rs569108 (Gly237Glu) in MS4A2, and rs1805015 (Ser478Pro) in IL4R (both for asthma and atopic asthma) and rs2787095 in ADAM33 (only for asthma) (data not shown). This evidence concerns the gene IL4 and atopic asthma.
