Clear cell renal cell carcinoma (ccRCC) exhibits high recurrence and metastasis rates. Although target therapy has significantly improved the prognosis of some patients with ccRCC, the median survival rate remains poor. Thus, there remains a need for the identification of novel potential targets for diagnosis and therapy. Here, we screened differentially expressed genes between ccRCC and normal tissues through analyzing The Cancer Genome Atlas database. We identified 55 up‐regulated and 67 down‐regulated genes associated with poor prognosis. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway analysis revealed that these genes were associated with glycometabolic process, complement and coagulation cascades. In addition, the eight down‐regulated genes ( HRG , FABP1 , ALDOB , PCK1 , HAO2 , CASR , PLG , and HMGCS2 ) and two up‐regulated genes ( SERPINE1 and TYROBP ) were filtered out. Finally, TYROBP was selected through repeated verification of various databases. High expression of TYROBP is associated with low survival rate in ccRCC, is closely related to immune cell infiltration and is coexpressed with Programmed cell death protein‐1( PD‐1 ) and Cytotoxic T lymphocyte‐associated antigen‐4( CTLA‐4 ). In conclusion, TYROBP may have potential for diagnosis and treatment of ccRCC.
