As a confirmation of the major role of this cytokine in EoE, the TSLP locus (5q22) is highly associated with EoE in multiple GWAS studies (Sherrill et al., 2010; Kottyan et al., 2014, 2021; Namjou et al., 2014; Sleiman et al., 2014). The gene discussed is TSLP; the disease is eosinophilic esophagitis.
