The methylation-based classification suggested anaplastic pleomorphic xanthoastrocytoma (-like) (PXA, score 0.99, Classifier 12.5), no MGMT promotor methylation, and the derived CNV profile indicated a homozygous deletion (HD) of CDKN2A/B. This evidence concerns the gene CDKN2A and pleomorphic xanthoastrocytoma.
