The genes that can be evaluated further are Th2-related genes (interleukin 4 (IL-4), interleukin-5 (IL-5), and interleukin-13 (IL-13)), transforming growth factor-β (TGF-β), mucin (MUC) genes (MUC5AC, MUC5B), Signal Transducer and Activator of Transcription 6 (STAT6), and forkhead box A2 (FOXA2) which are closely involved in asthma onset and progression. The gene discussed is MUC5B; the disease is asthma.
