Mitelman Database of Chromosome Aberrations and Gene Fusions in Cancer

Searching the Database

The information in the Mitelman Database of Chromosome Aberrations and Gene Fusions in Cancer relates chromosomal aberrations to tumor characteristics, based either on individual cases or associations. All the data have been manually culled from the literature by Felix Mitelman, Bertil Johansson, and Fredrik Mertens.

CGAP has developed six web search tools to help you analyze the information within the Mitelman Database:

  • The Cases Quick Searcher allows you to query the individual patient cases using the four major fields: aberration, breakpoint, morphology, and topography.
  • The Cases Full Searcher permits a more detailed search of the same individual patient cases as above, by including more cytogenetic field choices and adding search fields for patient characteristics and references.
  • The Molecular Biology Associations Searcher does not search any of the individual patient cases. It searches studies pertaining to gene rearrangements as a consequence of cytogenetic aberrations.
  • The Clinical Associations Searcher does not search any of the individual patient cases. It searches studies pertaining to clinical associations of cytogenetic aberrations and/or gene rearrangements.
  • The Recurrent Chromosome Aberrations Searcher provides a way to search for structural and numerical abnormalities that are recurrent, i.e., present in two or more cases with the same morphology and topography.
  • The Reference Searcher queries only the references themselves, i.e., the references from the individual cases and the molecular biology and clinical associations.
