CNAs among diffuse PLGGs. (A) Fraction of the genome altered by CNAs is lower among diffuse PLGGs compared with adult LGGs and high-grade gliomas (P < 10⁻⁶). Blue bars indicate medians. (B) Amplifications (red) and deletions (blue) among 44 diffuse PLGGs (x axis) across the genome (y axis) ordered by copy-number status. Significance (x axis) of (C) arm-level and (D) focal deletions (Left, blue) and amplifications (Right, red) across the genome (y axes). Putative gene targets within the peak regions are indicated where known.
