TCGA history • TCGA is a project, begun in 2005, to catalogue genetic mutations responsible for cancer, using genome sequencing. • TCGA is supervised by the Center for Cancer Genomics and the National Human Genome Research Institute. A three-year pilot project, begun in 2006, focused on characterization of three types of human cancers: glioblastoma, lung, and ovarian cancer. • In 2009, it expanded into phase II, which planned to complete the genomic characterization and sequence analysis of 20–25 different tumor types by 2014 • Gene expression (RNA-seq and array), copy number variation (array and genome sequencing), SNP genotyping (GGS and WES), DNA methylation (array and RBSS), microRNA profiling, proteomics (RPPA), and chromatin accessibility (ATAC-seq) • TCGA have published ~70 research articles. • There are 3554 authorized requesters associated with TCGA study (currently)
