CDKN2A and soft tissue sarcoma: From a biomolecular point of view, GS has mutations in common with soft tissue sarcoma due to involvement in the promoter of the Telomerase reverse transcriptase gene (pTERT), Tumor Protein 53 (TP53), Neurofibromin 1 (NF1), Cyclin-dependent kinase inhibitor 2A (CDKN2A), Cyclin-dependent kinase inhibitor 2B (CDKN2B) and Retinoblastoma associated Protein Type 1 (RB1) [60,62].
