Megjegyzések:	Pilocytic astrocytoma (PA) is the most common brain tumor in children but israre in adults, and hence poorly studied in this age group. We investigated 222 PA andreport increased aneuploidy in older patients. Aneuploid genomes were identified in45% of adult compared with 17% of pediatric PA. Gains were non-random, favoringchromosomes 5, 7, 6 and 11 in order of frequency, and preferentially affecting noncerebellarPA and tumors with BRAF V600E mutations and not with KIAA1549-BRAFfusions or FGFR1 mutations. Aneuploid PA differentially expressed genes involved inCNS development, the unfolded protein response, and regulators of genomic stabilityand the cell cycle (MDM2, PLK2), whose correlated programs were overexpressedspecifically in aneuploid PA compared to other glial tumors. Thus, convergence of pathways affecting the cell cycle and genomic stability may favor aneuploidy in PA, possiblyrepresenting an additional molecular driver in older patients with this brain tumor.
