Affymetrix 250K StyI SNP array data across multiple human cancer types


A powerful way to discover key genes playing causal roles in oncogenesis is to identify genomic regions that undergo frequent alteration in human cancers. We have reported high-resolution analyses of somatic copy-number alterations (SCNAs) from 3131 cancer specimens, belonging largely to 26 histological types. We identify 158 regions of focal SCNA that are altered at significant frequency across multiple cancer types, of which 122 cannot be explained by the presence of a known cancer target gene located within these regions. Several candidate genes and families are enriched among these regions of focal SCNA, including members of the BCL2 family of apoptosis regulators and the NF-
