KYNU and allergic disease: The odds ratios (95% confidence intervals, CI) for allergic diseases per standard deviation increase in genetically predicted protein levels were as follows: TNFAIP3 0.97 (0.95–0.99), LAYN 1.09 (1.01–1.18), TLR1 0.89 (0.79–1.00), IL1RL2 0.96 (0.95–0.97), IL1R1 1.04 (1.02–1.06), IL1RL1 1.03 (1.02–1.03), IL6R 1.01 (1.00–1.01), KYNU 1.01 (1.00–1.02), ITPKA 1.07 (1.03–1.11) and ERBB3 0.95 (0.93–0.97) (Figure 3).
