We then constructed a co-expression network of immune-related ASEs and immune-cell-related DERBPs and finally identified that the A5′SS event of the CTSB gene correlates with six DERBPs (MBNL2, UTP15, PHF10, TST, EXOSC8, and SYNCRIP) in CAD patients. The gene discussed is CTSB; the disease is coronary artery disorder.
