In a study of n = 14 NF2-SWN meningioma and n = 15 sporadic NF2-altered meningioma, Teranishi et al. (2023) showed similarly low NF2 gene expression, no distinct separation by PCA, and no significant difference between NF2-SWN and NF2-altered sporadic meningioma in immune infiltration score by CIBERSORTx [47]. This evidence concerns the gene NF2 and meningioma.
