The top IL18R1 SNP rs2001461 with an iHS CEU score of 4.544 was associated with blood protein (IL18R1) measurement, while two other SNPs were associated with serum ST2 (the IL1RL1 gene product) measurement (rs1420103) and atopic eczema (rs6419573). This evidence concerns the gene IL1RL1 and atopic eczema.
