COSMIC: mining complete cancer genomes in the Catalogue of Somatic Mutations in Cancer

COSMIC (http://www.sanger.ac.uk/cosmic) curates comprehensive information on somatic mutations in human cancer. Release v48 (July 2010) describes over 136 000 coding mutations in almost 542 000 tumour samples; of the 18 490 genes documented, 4803 (26%) have one or more mutations. Full scientific literature curations are available on 83 major cancer genes and 49 fusion gene pairs (19 new cancer genes and 30 new fusion pairs this year) and this number is continually increasing. Key amongst these is TP53, now available through a collaboration with the IARC p53 database. In addition to data from the Cancer Genome Project (CGP) at the Sanger Institute, UK, and The Cancer Genome Atlas project (TCGA), large systematic screens are also now curated. Major website upgrades now make these data much more mineable, with many new selection filters and graphics. A Biomart is now available allowing more automated data mining and integration with other biological databases. Annotation of genomic features has become a significant focus; COSMIC has begun curating full-genome resequencing experiments, developing new web pages, export formats and graphics styles. With all genomic information recently updated to GRCh37, COSMIC integrates many diverse types of mutation information and is making much closer links with Ensembl and other data resources.

COSMIC: exploring the world's knowledge of somatic mutations in human cancer

COSMIC, the Catalogue Of Somatic Mutations In Cancer (http://cancer.sanger.ac.uk) is the worlds largest and most comprehensive resource for exploring the impact of somatic mutations in human cancer. Our latest release (v70; Aug 2014) describes 2 002 811 coding point mutations in over one million tumor samples and across most human genes. To emphasize depth of knowledge on known cancer genes, mutation information is curated manually from the scientific literature, allowing very precise definitions of disease types and patient details. Combination of almost 20 000 published studies gives substantial resolution of how mutations and phenotypes relate in human cancer, providing insights into the stratification of mutations and biomarkers across cancer patient populations. Conversely, our curation of cancer genomes (over 12 000) emphasizes knowledge breadth, driving discovery of unrecognized cancer-driving hotspots and molecular targets. Our high-resolution curation approach is globally unique, giving substantial insight into molecular biomarkers in human oncology. In addition, COSMIC also details more than six million noncoding mutations, 10 534 gene fusions, 61 299 genome rearrangements, 695 504 abnormal copy number segments and 60 119 787 abnormal expression variants. All these types of somatic mutation are annotated to both the human genome and each affected coding gene, then correlated across disease and mutation types.

The COSMIC (Catalogue of Somatic Mutations in Cancer) database and website

The discovery of mutations in cancer genes has advanced our understanding of cancer. These results are dispersed across the scientific literature and with the availability of the human genome sequence will continue to accrue. The COSMIC (Catalogue of Somatic Mutations in Cancer) database and website have been developed to store somatic mutation data in a single location and display the data and other information related to human cancer. To populate this resource, data has currently been extracted from reports in the scientific literature for somatic mutations in four genes, BRAF, HRAS, KRAS2 and NRAS. At present, the database holds information on 66 634 samples and reports a total of 10 647 mutations. Through the web pages, these data can be queried, displayed as figures or tables and exported in a number of formats. COSMIC is an ongoing project that will continue to curate somatic mutation data and release it through the website.

The Catalogue of Somatic Mutations in Cancer (COSMIC).

COSMIC is currently the most comprehensive global resource for information on somatic mutations in human cancer, combining curation of the scientific literature with tumor resequencing data from the Cancer Genome Project at the Sanger Institute, U.K. Almost 4800 genes and 250000 tumors have been examined, resulting in over 50000 mutations available for investigation. This information can be accessed in a number of ways, the most convenient being the Web‐based system which allows detailed data mining, presenting the results in easily interpretable formats. This unit describes the graphical system in detail, elaborating an example walkthrough and the many ways that the resulting information can be thoroughly investigated by combining data, respecializing the query, or viewing the results in different ways.

COSMIC (the Catalogue of Somatic Mutations in Cancer): a resource to investigate acquired mutations in human cancer

The catalogue of Somatic Mutations in Cancer (COSMIC) (http://www.sanger.ac.uk/cosmic/) is the largest public resource for information on somatically acquired mutations in human cancer and is available freely without restrictions. Currently (v43, August 2009), COSMIC contains details of 1.5-million experiments performed through 13 423 genes in almost 370 000 tumours, describing over 90 000 individual mutations. Data are gathered from two sources, publications in the scientific literature, (v43 contains 7797 curated articles) and the full output of the genome-wide screens from the Cancer Genome Project (CGP) at the Sanger Institute, UK. Most of the world’s literature on point mutations in human cancer has now been curated into COSMIC and while this is continually updated, a greater emphasis on curating fusion gene mutations is driving the expansion of this information; over 2700 fusion gene mutations are now described. Whole-genome sequencing screens are now identifying large numbers of genomic rearrangements in cancer and COSMIC is now displaying details of these analyses also. Examination of COSMIC’s data is primarily web-driven, focused on providing mutation range and frequency statistics based upon a choice of gene and/or cancer phenotype. Graphical views provide easily interpretable summaries of large quantities of data, and export functions can provide precise details of user-selected data.

COSMIC: somatic cancer genetics at high-resolution

COSMIC, the Catalogue of Somatic Mutations in Cancer (http://cancer.sanger.ac.uk) is a high-resolution resource for exploring targets and trends in the genetics of human cancer. Currently the broadest database of mutations in cancer, the information in COSMIC is curated by expert scientists, primarily by scrutinizing large numbers of scientific publications. Over 4 million coding mutations are described in v78 (September 2016), combining genome-wide sequencing results from 28 366 tumours with complete manual curation of 23 489 individual publications focused on 186 key genes and 286 key fusion pairs across all cancers. Molecular profiling of large tumour numbers has also allowed the annotation of more than 13 million non-coding mutations, 18 029 gene fusions, 187 429 genome rearrangements, 1 271 436 abnormal copy number segments, 9 175 462 abnormal expression variants and 7 879 142 differentially methylated CpG dinucleotides. COSMIC now details the genetics of drug resistance, novel somatic gene mutations which allow a tumour to evade therapeutic cancer drugs. Focusing initially on highly characterized drugs and genes, COSMIC v78 contains wide resistance mutation profiles across 20 drugs, detailing the recurrence of 301 unique resistance alleles across 1934 drug-resistant tumours. All information from the COSMIC database is available freely on the COSMIC website.

COSMIC: High‐Resolution Cancer Genetics Using the Catalogue of Somatic Mutations in Cancer

COSMIC (http://cancer.sanger.ac.uk) is an expert‐curated database of somatic mutations in human cancer. Broad and comprehensive in scope, recent releases in 2016 describe over 4 million coding mutations across all human cancer disease types. Mutations are annotated across the entire genome, but expert curation is focused on over 400 key cancer genes. Now encompassing the majority of molecular mutation mechanisms in oncogenetics, COSMIC additionally describes 10 million non‐coding mutations, 1 million copy‐number aberrations, 9 million gene‐expression variants, and almost 8 million differentially methylated CpGs. This information combines a consistent interpretation of the data from the major cancer genome consortia and cancer genome literature with exhaustive hand curation of over 22,000 gene‐specific literature publications. This unit describes the graphical Web site in detail; alternative protocols overview other ways the entire database can be accessed, analyzed, and downloaded.

Abstract 62: COSMIC: Combining the world's knowledge of somatic mutation in human cancer

COSMIC, the Catalogue Of Somatic Mutations In Cancer (http://cancer.sanger.ac.uk) is the world9s largest and most comprehensive online resource for exploring the impact of somatic mutations in human cancer. Live since 2004, the 71st release (Nov 2014) describes over 2 million mutations in more than 1 million tumour samples across most human genes. To emphasise depth of knowledge on known cancer genes, mutation information is curated manually from the scientific literature, allowing very precise definitions of disease types and clinically relevant patient details. Combination of over 20,000 published studies gives substantial resolution of how mutations and phenotypes relate in human cancer, providing insights into the stratification of populations and new diseases behind known biomarkers. Conversely, our curation of over 15,000 cancer genome studies emphasises knowledge breadth, driving discovery of new unrecognised cancer-driving hotspots and molecular targets. Our high-resolution curation approach is globally unique, giving substantial insight into molecular biomarkers in human oncology. For example, BRAF is well characterized in skin melanoma, transiently treatable with inhibitors such as Vemurafenib. It is also well known in colorectal cancer, which is largely non-responsive to BRAF inhibitors. COSMIC9s unique approach demonstrates the impact of BRAF mutations in much less well-known cancers, for instance, Hairy Cell Leukaemia (89% of samples mutated) and Langerhans Cell Histiocytosis (49%), both of which respond remarkably well to BRAF inhibitors. Converse to skin melanoma, our curations suggest BRAF has a minimal role in Uveal melanoma (6% of Uveal tumors mutated for BRAF), with higher mutation rates in other genes (particularly GNA11, BAP1 and GNAQ), suggesting different mechanisms behind this disease. In addition to describing over two million coding point mutations across cancer, COSMIC also details more than six million non-coding mutations, 10,567 gene fusions, 61,232 genome rearrangements, 702,652 abnormal copy number segments, and more than 6 million abnormal expression variants. All these types of somatic mutation are annotated to both the human genome and each affected coding gene, then correlated across disease and mutation types. As increasing amounts of genetic data are gathered into COSMIC across human cancer, our annotations are beginning to emphasise events with a higher impact in cancer, highlighting the more functional coding mutations and major amplifications and deletions. This concept of high-impact data is being extended across the entire COSMIC system, much more strongly defining genes and mutations which drive oncogenesis. Citation Format: Simon A.

Mining cancer genomes in COSMIC

COSMIC, The Catalogue Of Somatic Mutations In Cancer [http://cancer.sanger.ac.uk], is one of the largest repositories for somatic mutational events in human cancer. Data in COSMIC are curated from multiple sources, including from over 14,310 scientific publications, and are alongside data from the Cancer Genome Project at the Sanger Institute and global international consortia, such as The Cancer Genome Atlas and the International Cancer Genome Consortium. The COSMIC database currently accommodates over 300,000 mutations across 750,000 analyzed samples from 21,850 genes (COSMIC v60, July 2012). The Cancer Gene Census [http://cancer.sanger.ac.uk/cancergenome/projects/census/] is a list of almost 500 known cancer genes for which mutations have been identified as causally implicated in cancer. These genes are prioritized for full literature curation. The collection of whole exome and genome sequencing data in COSMIC continues to grow at a rapid pace. There are: 17,614 coding mutations, 84,747 non-coding variants in 396 whole genome screens; 121,619 coding mutations and 12,949 non-coding variants as result of 1,266 full exome sequencing; 3,512 structural mutations derived from 77 rearrangement screens. The data overview for each whole genome screen is presented using Circos, for example, the NCI-H209 Circos summary [http://cancer.sanger.ac.uk/cosmic/sample/overview?id=688013]. Analyzing information from whole genome sequencing can greatly enhance the chance of discovering novel genes implicated in human cancer. Unlike hot spot screening of gene regions where somatic mutations are most frequent, the use of whole genome data can identify all mutations in all genes, providing much more expansive annotations to recurrence analysis as used to discover new cancer genes. For instance, there are recurrent somatic mutations identified in genes, for example: SPOP in 19 prostate samples; SDK1 in 20 large-intestine samples. There are several ways to access and analyze the data in COSMIC. The website allows data viewing in a genomic context supported by GBrowse while maintaining our gene-centric perspective. New additional features include a filter for excluding identified SNPs from the 1000 Genomes Project, and displaying Pfam domains and links to biological pathways for selected genes. For mining a large dataset, COSMICmart (an instance of BioMart) is a tool for downloading user-customized datasets federated with external databases such as Ensembl and Uniprot. Moreover, we provide data export in multiple formats and Oracle database export through the FTP site [ftp://ftp.sanger.ac.uk/pub/CGP/cosmic]. In addition to somatic mutation data, we have integrated the data from the Genomics of Drug Sensitivity in Cancer Project [http://www.cancerrxgene.org], which is screening a wide range of anticancer therapeutics against over 1,000 genetically characterized human cancer cell lines. Data analysis is becoming increasingly challenging due to the rapid expansion in cancer genome sequencing capacity. COSMIC is a major cancer genetics resource aiming to help such investigations, providing a centralized somatic mutations database with a wide suite of tools for its examination.
