BAP1 and meningioma: While histologic features are an important part of the World Health Organization (WHO) grading for meningiomas, some molecular alterations (such as mutations in SWI/SNF-Related, Matrix-Associated, Actin-Dependent Regulator of Chromatin, Subfamily E, Member 1 (SMARCE1), BRCA1-Associated Protein-1 (BAP1), and Telomerase Reverse Transcriptase (TERT) promoters) are relevant as part of the subtyping and grading criteria [2].
