In addition, our GSEA analysis showed that in renal cell carcinoma, the high expression of EFHD2 was mainly concentrated in ALLOGRAFT_REJECTION, REACTIVE_OXYGEN_SPECIES_PATHWAY, INTERFERON_GAMMA_RESPONSE, IL6_JAK_STAT3_SIGNALING, INTERFERON_ALPHA_RESPONSE, and other signal pathways. The gene discussed is EFHD2; the disease is hereditary clear cell renal cell carcinoma.
