Regarding the SHH-activating meningiomas (n = 7), while one of the three complex rearrangements was found in a non-skull base meningioma, all simple SVs (n = 4) were found in skull base ones (P = 0.43; Table 1, Supplementary Data 1 and 10). The gene discussed is SHH; the disease is skull base meningioma.
