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.

Table Information

Hide

The table currently shows only high value (numeric) copy number data. Copy number segments are excluded if the total copy number and minor allele values are unknown.

Click here to include all copy number data. For more detailed information about copy number data and gain/loss definitions click here.

Sample Gene Expression Expr Level (Z-Score)

Over Expressed; Z-Score > 2.0

Under Expressed; Z-Score < -2.0

Normal; Z-Score within the range -2.0 to 2.0

CN Type Minor Allele Copy Number CN Segment Posn. Average Ploidy

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

2. For TCGA samples, the ASCAT algorithm was used to calculate the average ploidy.

3. For CGP samples, the PICNIC algorithm was used to calculate the average ploidy.

CNV
This tab shows a summary table with counts (number of samples) for CNV gain/loss and under/over expression for all genes. [more details]

The results shown in this table are derived from all copy number data. This includes non-numeric data with descriptive definitions of gain/loss.
