IL1RL1 and respiratory system disorder: We did not observe SNP eQTL effects in the biopsy and bronchial brush data sets generated from tissue samples obtained from volunteers without respiratory diseases, which is in contrast to a recent study that identified 3 IL1RL1 SNPs (rs12712135; tagged by Signal B; rs1420088 [r2 = 0.98], rs1041973 and rs10185897), which showed association with membrane IL1RL1 mRNA in bronchial brush samples from asthma patients (38).
