The CpG sites cg15059804 (ZNF362) and cg11660018 (PRSS23) were found to be associated with asthma in an EWAS conducted in lung cells;47 cg11660018 (PRSS23) and cg23771366 (PRSS23) were suggested to have a causal effect on lung function in another EWAS conducted in blood; this study was followed up by a two-sample MR analysis.7 This evidence concerns the gene PRSS23 and asthma.
