It is increasingly appreciated that the driver mutations of meningiomas are associated with particular histopathologic subtypes and with anatomic locations in the cranium.6, 7, 9, 18 Recent work has shown that a subset of rhabdoid meningiomas, but not meningiomas of other histological subtypes, harbor mutations in the tumor suppressor gene BAP1. 11 Across high-grade meningiomas, we found that the rhabdoid subtype was associated with a significantly lower incidence of chromosome 1p losses compared with other high-grade meningiomas (p = 0.002, Fig. 2a), consistent with a distinct pathogenesis. Here, BAP1 is linked to meningioma.
