Grade-wise comparisons on MGI (benign) vs MGII (atypical) meningiomas revealed prominent involvement of TIMM50, SEC23A, MTAP, RPS23, and ADRM1 based on the concordance analysis of highly ranked features from across 20 Machine Learning randomized iterations obtained via the methods of the Ball group (28) (Figures 3A,B and Supplementary Data 4B, 5). Here, MTAP is linked to meningioma.
