  1. Regions of copy number gain containing more than one amplification with intensity ratio (IR) >2.0, as well as frequency of single copy gain (IR 1.2–2.0) in these regions. aMap positions and cytogenetic locations are based on data available from UCSC genome browser (July 2003 freeze) [35]. bRegion boundaries were determined by the next bacterial artificial chromosome with different copy number.
