Classical and mesenchymal subtypes consistently overlap at the transcriptomic level, but the mesenchymal subtype also presents an inactivation of neurofibromin 1 (NF1), overexpression of the YKL-40 gene, and proteins of NF-κB network, which is consistent with the inflammatory features that characterise this tumour. Here, NFKB1 is linked to neoplasm.
