  2. aData compiled from 407 PB and 600 CB.
  3. blog2 mean green/red ratios more than the mean +2.5 SD (~ 0.25) were considered high amplifications or gains of the indicated copy number, and less than the mean -2.5 SD (~ -0.25) were considered high losses of the copy number.
  4. cperformed by karyotype and FISH analyses. FISH analyses were performed using specific BAC clones.
