The Catalogue of Somatic Mutations in Cancer (COSMIC) was designed by the Sanger Institute to house and exhibit information about somatic mutation and associated details and "contains information relating to human cancers." The COSMIC database draws on information from the primary literature, and allows users to browse by gene or tissue. In order to present users with "a consistent view of the data a histology and tissue ontology has been created and all mutations are mapped to a single version of each gene." The COSMIC site also links to other Sanger Institute projects such as the Cancer Genome Project. Links are provided to a number of other database resources as well.
