CTSB and COVID-19: The combined gene network showed an obvious better integration than that of COVID‐19– and GBS‐associated genes alone, with several clusters previously detached from the main network (eg TLR7‐CTSL/CTSB/TLR3, LSAMP‐FCGR3B‐FCGR3A, TLR4‐CD14 clusters in COVID‐19; PMP22‐LAMC2 cluster in GSB) now rejoined (Figure 2A).
