According to Reactome analysis in Figure 7, HOXC4 might be involved in immune-related functions, cell cycle and tumor metabolism in multiple cancers, including the modulation of innate/adaptive immune system, cytokine/interferon/interleukins signaling in the immune system, neutrophil degranulation, B cell receptors, immunoregulatory interactions, class I MHC mediated antigen processing and presentation and several immune-related signaling pathways. The gene discussed is HOXC4; the disease is cancer.
