However, a significant influence of maternal AD on increased IL-13 concentration [MR (95% CI): 1.13 (1.01–1.27); adj.MR (95% CI): 1.17 (1.04–1.32), Figure 2B] was observed, which was sustained even after additionally adjusting for asthma [adj.MR (95% CI) = 1.18 (1.04–1.33), n = 292, p = 0.007]. The gene discussed is IL13; the disease is asthma.
