Among them, EIF4B_S422 and EIF4B_T420 phosphorylation were not only specifically highly expressed in the C1 subtype of LM samples (p < 0.05), but also significantly correlated with poor prognosis (log‐rank p < 0.05, Figure 6I; Figure S6G, Supporting Information). The gene discussed is EIF4B; the disease is lymphangioma.
