SLC22A5 and asthma: Group two consisted of 13 genes co-mentioned frequently with allergy-related terms since, but not before, 2007: ORMDL3, GSDMB, ZPBP2, IKZF3, GSDMA, IL6R, CHIT1, FCER1G, SLC22A5, WDR36, IL18RAP, HLA-DQA2 and NDFIP1. The first five are located in the same asthma risk locus, and were first suspected to contribute to asthma pathophysiology because of GWAS findings.
