IDH1-mutant cases were again excluded (n = 14), with genetic profiles identical to that described in adults for astrocytic tumors (13/14 TP53, 7/14 ATRX mutations), and oligodendroglial tumors (1p19q co-deletion, TERT promoter, CIC, FUBP1 mutations) entirely absent (Figure S6C). The gene discussed is TERT; the disease is oligodendroglial tumor.
