In this work, we examined the patterns of somatic copy number alterations (SCNA) in cancer genomes, and investigated the role of DNA methylation in neural stem cells (NSCs). We identified features including distance to telomere, distance to centromere and direct repeats, that are predictive of SCNA patterns. We found a number of genes, such as TP53 and WWOX, located in these broken regions in osteosarcoma. Finally, we uncovered an injury-induced epigenetic program that encompasses the decommissioning of developmental transcription factors selectively in NSCs.
