Chromosomal aberration plots of a hyperdiploidy leukaemia patient based on the Affymetrix Human Mapping 100K Set. A chromosomal aberration plot consists of an extended allele frequency plot, an allelic imbalance (AI) plot, and a loss of heterozygosity (LOH) plot from the top to the bottom (Appendix B). In the extended allele frequency plot, a lot of the AI SNPs (red points) were found on whole chromosomes 6, 8, 10, 14, 17, 18 and 19. In the AI plot, a whole-chromosome region of AI (red bar in the top panel) was found on chromosomes 6, 8, 10, 14, 17, 18 and 19. In the LOH plot, a whole-chromosome region of LOH (red bar in the top panel) was found on chromosomes 2 and 19.
