Illumina BeadStudio results for the tumor DNA. a Chromo-some 9 shows a split in the B allele frequency with no change in the log R ratio, consistent with a CN LOH event for the whole chromosome. There is also a homozygous deletion in 9p21.3 that contains the CDKN2A locus. b Chromosome 21 shows a split in the B allele frequency and an increase in the log R ratio consistent with a duplication of the whole chromosome in very few cells. There are also three regions of deletion. c Chromosome 22 has a 2.5 Mb region of heterozygous deletion in q11.21 that is present in all cells, and represents the underlying germline deletion
