Cytogenetic Resources and Information

Area of Science:

• Oncology
• Genetics
• Bioinformatics

Background:

• Cancer cytogenetics involves studying chromosome aberrations and gene fusions.
• The field has expanded to cytogenomics, integrating diverse genomic data.
• Several key databases and resources support cancer cytogenetics research.

Purpose of the Study:

• To identify and describe major databases and resources for cancer cytogenetics and cytogenomics.
• To highlight the importance of complementary genomic resources and standardized nomenclature.
• To raise awareness about the sustainability challenges facing these critical scientific databases.

Main Methods:

• Review and compilation of prominent cancer cytogenetics databases (Mitelman, Atlas, COSMIC).
• Identification of complementary resources including general genomic databases, cancer genomic portals (TCGA, ICGC), and specialized databases (gene fusions, CGH, copy number variation, mutations).
• Inclusion of nomenclature systems (ISCN, ICD-O, HGNC) for standardized communication.

Main Results:

• The Mitelman Database, Atlas of Genetics and Cytogenetics in Oncology and Haematology, and COSMIC are primary resources.
• A wide array of complementary databases support cytogenomic research, covering sequence data, genomic variations, and gene information.
• Standardized nomenclature systems facilitate consistent data interpretation and reporting.

Conclusions:

• Effective cancer cytogenetics and cytogenomics research relies on a network of specialized and general databases.
• Free and open access to data is crucial for the scientific community.
• The sustainability of these vital resources is threatened by disengaging institutional stakeholders, risking their disappearance.
