Some of their gene-specific findings overlap with specific DNAm marks in our data for asthma: FeNO and environment IgE sensitization (lower DNAm of IL-4, ACOT7, ZFPM1), or FeNO and allergic asthma (RUNX3); whereas other findings revealed different DNAm marks, although the functions of the differentially methylated genes were similar to those reported in our findings (oxidative stress, T cell differentiation). This evidence concerns the gene IL4 and allergic asthma.
