The 17q12-q21 common polymorphisms associated with asthma delineate a genomic interval that encompasses five protein-coding genes: IKAROS family zinc finger 3 (Aiolos) (IKZF3), zona pellucida binding protein 2 (ZPBP2), gasdermin B (GSDMB), ORMDL sphingolipid biosynthesis regulator 3 (ORMDL3), and gasdermin A (GSDMA). Here, IKZF3 is linked to asthma.
