In the meta‐analysis of the FinnGen cohort, seven proteins showed significant associations, and the odds ratios (95% confidence intervals, CI) for allergic diseases per standard deviation increase in genetically predicted protein levels were as follows: TNFAIP3 0.87 (0.78–0.96), IL1RL2 0.85 (0.80–0.92), IL1R1 1.14 (1.06–1.21), IL6R 1.03 (1.01–1.04), KYNU 1.04 (1.00–1.07), LRP11 1.04 (1.02–1.06) and ITPKA 1.74 (1.48–2.04). Here, IL1R1 is linked to allergic disease.
