The Recurrent Chromosome Aberrations in Cancer Database Searcher
  • Brief instructions for searching the database:
    • You must choose one or both of the following two fields: Structural Aberrations and Numerical Aberrations.
    • If you choose Structural Aberrations, you must select at least one of the following fields: Breakpoint, Topography, Morphology, or Gene.
    • If you choose Numerical Aberrations, you must select at least one of the following fields: Chromosome, Topography, Morphology.
    • You may select only one item in each pulldown menu
    • Press Retrieve.
  • A successful search returns a table, with the following headings and entries:
    • Breakpoint, with each entry linked to the OMIM Gene Map (this column is returned only for structural aberrations)
    • Abnormality
    • Morphology, with each entry linked to a similar table that describes all abnormalities with this morphology.
    • Topography, with each entry linked to a similar table that describes all abnormalities at this topography
    • Number of cases, hyperlinked to the list of applicable cases
    • Genes
