Furthermore, the tumor cells were negative for mouse double minute 2 (MDM2) and cyclin-dependent kinase 4 (CDK4), excluding liposarcoma; however, BRG1, BRCA-associated protein 1 (BAP1), integrase interactor 1 (INI1), and histone H3 lysine 27 trimethylation (H3K27ME3) were retained. Here, SMARCB1 is linked to neoplasm.
