Previous genome-wide association studies (GWAS) have identified numerous single nucleotide polymorphisms (SNPs) in genes associated with the risk of asthma (6), such as orosomucoid 1-like protein 3 (ORMDL3) gene rs7216389 (7), interleukin-6 (IL-6) gene rs1800795 (8), and thymic stromal lymphopoietin (TSLP) gene rs1837253 (9). The gene discussed is TSLP; the disease is asthma.
