The third most commonly altered gene in anaplastic PXA was TERT, with 47% (7/15) harboring TERT alterations, either gene amplification (n = 2) or promoter hotspot mutation (n = 5).
BRAF mutation at T1799 > A (V600E) was detected in 4/12 (33.3%) PXA and 4/8 (50.0%) eGBM, while TERT-p mutation was detected at C228 > T in 2/12 (16.7%) PXA and at C250 > T in 1/8 (12.5%) eGBM.
