SMARCE1 mutation screening in classification of clear cell meningiomas.

These results expand the spectrum of pathogenic variants in SMARCE1 and show that mutation screening can help to facilitate meningioma classification. This may have implications for prognosis and future clinical management of patients, as CCMs are classed as grade II tumours, while microcystic and meningothelial meningiomas are classed as grade I.
