The minimal overlapping region of 36 Mbp at 6q14.1q22.31 covered a total of 175 genes, including four genes from the Cancer Gene Census database (PRDM1, FOX03, ROS1, GOPC), while gains of 1q25.1q32.2 of 34 Mbp encompassed a total of 269 genes, among which six genes are known to be involved in cancer pathogenesis (ABL2, TPR, CDC73, MDM4, ELK4, SLC45A3). This evidence concerns the gene MDM4 and cancer.
