<prompt> Answer this question truthfullyCould you provide me with the correct phrasing of the sentence? Because, What is the pathophysiology of meningioma? is already in proper English.  <response>: <reason> Genes involved in the pathogenesis of meningioma include: Neurofibromatosis 2 NF2 gene on chromosome 22 MEG3 maternally expressed gene 3: Loss of expression, genomic DNA deletion, and promoter methylation on chromosome 14q32. NDRG2 N-Myc downstream-regulated gene 2: Down regulation of this gene expression at the mRNA level is associated with the malignant progression and predisposition to recurrence of meningiomas. SMARCE1 SWISNF chromatin-remodeling complex subunit gene: Heterozygous loss-of-function mutation. Its is commonly seen in meningiomas with clear cell histology and those located in the spine. SMARCB1: Predisposes to multiple meningiomas preferentially in the falx cerebri. TERT promoter mutation: Seen in meningiomas undergoing malignant histological progression. TRAF7 AKT1 KLF4 SMO PIK3CA
