NF2 and meningioma: In this study, the GSE216783 dataset contained 12/15 (80%) VS samples with known NF2 pathogenic variants, and although the NF2 status of the sporadic meningioma from GSE183655 were unavailable, 3/6 (50%) of these were confirmed to have a loss of 22q (the region in which the NF2 gene is located) (Supplementary Table 1).
