3. Fig 2
Schematic overview of IL1RL1 region, splice variants (IL1RL1-a and IL1RL1-b), and IL1RL1 SNPs with their LD structure within PIAMA. The upper line describes the nucleotide sequence. The second and third lines describe splice variant IL1RL1-a and IL1RL1-b, where blocks are exons and lines are introns. The table shows the LD between the SNPs in the PIAMA cohort with the thick lines representing blocks of high LD (D' 99% CI ≥ for 99% of SNP pairs).

4. Fig 3
Association of rs and rs with IL1RL1-a levels at ages 4 and 8 years (A and B) and eosinophils count (C and D). This figure shows the mean IL1RL1-a level with 95% CI of rs (A) and rs (B) at ages 4 and 8 years and the mean eosinophil counts for these SNPs (C and D). Frequency of genotypes is reported under the x-axis. ∗Significant associations after correction for multiple testing.

5. LD plot of IL1RL1, IL18R1, and IL18RAP SNPs
LD plot of IL1RL1, IL18R1, and IL18RAP SNPs. Pairwise LD (r2) among SNPs of IL1RL1, IL18R1, and IL18RAP with marked independent significantly associated SNPs with IL1RL1-a serum levels (red continuous circles) and eosinophil counts (dotted green circles).
