Somatic mutations in glioma cells. From the outsider, Tracks 1 and 2: numbering and cytobands of different chromosomes. Track 3: black bars showing the LOH-enriched loci in chromosomal regions, most prominently in 1p, 9p, 9q and 19q. Track 4: blue bars showing number of somatic indels of ≤ 30 bp per 5-Mb window (scale: 0-6). Track 5: red bars showing number of somatic SNVs per 5-Mb window (scale: 0-8). The cytogenetic locations of seven potential SNV hotspots displaying a density of somatic SNVs > 4, viz. greater than the sum of the Mean (= 1.5) plus two-times the standard deviation (= 1.9), per 5-Mb window are indicated as 11q13.4, 12q13, 16p13.1 etc.
