Up-regulation of mRNA expression in human chromosomal region 20q11.22-q11.23 (patient counts with coordinate up-regulation). Grayscale plot of cross-comparison of up-regulation patterns across patients for gene pairs in a particular region. Both, horizontal and vertical axes comprise the same genes in chromosomal order. In each square total counts of patients with consistent up-regulation in two genes are coded by different shades of gray. Dark squared regions along the diagonal indicate coordinated regulation in patient subgroups. Note, that many more patients show up-regulation as indicated by dark spots in this plot than down-regulation as indicated by dark spots in Figure 14. The known most frequently up-regulated genes in this region are EIF2S2, AHCY, ITCH, DNCL2A, ITG4BP, C20orf24, NDRGL3, RPN2 and CTNNBL1. Also note the gene C20orf110 alias TP53INP2 which is down-regulated in the majority of tumors.
