BK viral integration sites visualized in Integrated Genome Viewer. The top panel represents the normal and the lower tumor. A chimeric fusion is identified in the tumor with breakpoint in intron 9 of MACROD2 gene on chr 20. The fusion maps across half the reads to the human genome (gray) and the other half (colored) is unmapped. Blast of the unmapped sequences align to the BKV genome
