05-cytoData: Example Cytoband Data

Description Usage Format Author(s) Source References


This data set contains the genomic locations of cytobands along with loss-gain-fusion percentages for three group of samples.




A data matrix (cytobandLocations) containing 868 rows and 14 columns. Each row contains one of the cytobands defined in the 2016 update to ISCN nomenclature. The rownames are the standard cytoband names; for example, 1p36.33. The first five columns are the same as in the cytobandLocations data set. The remaining nine columns form three sets of three, recording the percentage of Loss, Gain, and Fusion events in three sets of samples, labeled "A", "B", and "C".

The cytoband locations were downloaded from the UCSC Genome Browser and synchronized with the list of cytobands in ISCN 2016. The percentages were computed using tools in this package from subsets of the Mitelman Database of Chromosome Aberrations and Gene Fusions in Cancer.
