Moreover, partial deletion of chromosome 9p, containing CDKN2A, is a frequent event specifically in ccRCC (among 20% in the TCGA cohort) [72]; results from an integrated proteogenomic analysis by the Clinical Proteomic Tumor Analysis Consortium showed that loss of chromosome 9p is associated with an upregulation of mTOR signaling effectors [73]. Here, MTOR is linked to nonpapillary renal cell carcinoma.
