LOH-profiling by SNP-mapping in a case of multifocal head and neck cancer

Figure 2 Single nucleotide polymorphism 50K Xbal genome-wide loss of heterozygosity profiling using the AffymetrixGeneChip Assay System. Regions of genomic deletions between 1.6 Mb and 8.1 Mb in size were identified on 5 chromosomes (red labeling). The x-axis shows physical position along the respective chromosome. The y-axis indicates -log10P values where homozygous stretches are due to loss of heterozygosity.
