In addition, other mutations affecting upstream kinases and regulators (TRAF3, CD40, BAFFR, and NIK) of this pathway, which promote NIK stability and subsequent activation of noncanonical NF‐κB, have been described in different cancer types [9, 10, 11, 12], including splenic marginal zone lymphomas, Hodgkin's lymphomas, and lung cancer. The gene discussed is MAP3K14; the disease is lung carcinoma.
