Figures

Distribution of genome wide aneuploidy (GAS) scores in healthy individuals and patients with benign (BN) or plexiform neurofibronas (PN) or MPNST.

**p < 0.01, ***p < 0.001.

Figure 2 with 1 supplement
Genome wide aneuploidy scores and detection of sub-chromosomal copy number changes in PDGFA, TERT, TBX1, EGFR, BRAF, EXT1, CDKN2A/B, PTEN, EXT2, EED, IDH2, TP53, NF1, and SUZ12 allow for detection of 50% of MPNST at 97% specificity.
Figure 2—figure supplement 1
Patients with MPNST demonstrated loss of SUZ12 on chromosome 17q.

Each dot represents a sub-chromosomal locus covered by RealSeqS.
