  1. Note: Each region’s genomic position is shown, the number of homozygous deletions (HDs), the combined p-value (and multiple testing-corrected q-value) indicating the probability that the enrichment in homozygous deletions is due to increased genomic instability (rather than due to positive selection), and the established or candidate tumour suppressor gene identified
  2. aCDKN2B and BIRC2 are candidate tumour suppressor genes with a high level of evidence. They are always lost together with CDKN2A and BIRC3, respectively, and are likely to contribute to positive selection of the homozygous deletions
  3. bPDE4D shows intragenic homozygous deletions, suggesting that these deletions may be gain-of-function rather than loss-of-function mutations
