Abstract
Clear cell renal cell carcinomas are characterized by 3p loss, and by inactivation of Von Hippel Lindau (VHL), a tumorsuppressor gene located at 3p25. Recently, SETD2, located at 3p21, was identified as a new candidate ccRCC tumor-suppressor gene. The combined mutational frequency in ccRCC tumors of VHL and SETD2 suggests that there are still undiscovered tumor-suppressor genes on 3p. We screened all genes on 3p for mutations in 10 primary ccRCC tumors using exome-sequencing. We identified inactivating mutations in VHL, PBRM1, and BAP1. Sequencing of PBRM1 in ccRCC-derived cell lines confirmed its frequent inactivation in ccRCC. PBRM1 encodes for BAF180, the chromatin targeting subunit of the SWI/SNF complex. BAP1 encodes for BRCA1 associated protein-1, involved in histone deubiquitination. Taken together, the accumulating data suggest an important role for aberrant chromatin regulation in ccRCC development. Hum Mutat 33:1059-1062, 2012. © 2012 Wiley Periodicals, Inc.

CNV Gene Sample Position Minor Allele Copy Number Average Ploidy

1. N/A represents cases where average ploidy value is not available( mostly ICGC samples). For some TCGA samples where minor allele information is not available the average ploidy value could not be calculated.

2. For TCGA samples, Ascat algorithm is used to calculate the average ploidy.

3. For CGP samples, Picnic algorithm is used to calculate the average ploidy.
