SNP-array and gene expression DNA microarray data mapped to chromosomal positions. Positions corresponding to the transcripts detected by the Affymetrix HGU133A/B expression microarray are plotted in green if they were detected and black if they were not detected; corresponding genomic positions of the Affymetrix 10 K SNP-Array probes are plotted in red if they hybridized to DNA in the ChIP on SNP-chip experiment (indicating the position of hyperacetylated histone H4), and grey if not. Ambiguous data points are not shown. All 22 autosomes and the X chromosome are represented. The Y chromosome is not considered in the SNP-Array used. Mb: megabases; SNP: Single Nucleotide Polymorphism.
