SCGB1A1 and asthma: Subsequent association tests carried out on this region revealed the importance of the genes MS4A2 (earlier FcεRI-β or β chain of the high-affinity receptor for IgE), SCGB1A1 (earlier uteroglobin or Clara cell secretory protein (CC16)), glutathione S-transferase pi (GSTP1) and GPR44 (earlier CRTH2) in asthma and asthma related phenotypes [1], [2], [3], [4].
