Whole exome sequencing in a case of sporadic multiple meningioma reveals shared NF2, FAM109B, and TPRXL mutations, together with unique SMARCB1 alterations in a subset of tumor nodules.

Abstract excerpt

Meningiomas are common intracranial tumors derived from arachnoid cells. Multiple meningiomas are occasionally present even in patients with no history of neurofibromatosis type 2, a condition that can cause the formation of this neoplasm. Previous studies have shown that most multiple meningiomas are monoclonal in origin. In this study, exome sequencing was performed on four meningiomas and the corresponding...
