Meningioangiomatosis (MA) is a rare, benign hamartomatous lesion found in cerebral cortex and leptomeninges. It occurs mostly in 5 - 15 year old children in form isolated or diffuse; the diffuse form may be associated with neurofibromatosis type 2 (NF2). The sporadic type in the adults is less common.The patient was a 37 year-old man with a long history of frontal headache. In suspected sinusit...
Schwannomas are encapsulated and slow grooving benign peripheral nerve tumors. They represent about one third of all benign primary spinal tumors. Most schwannomas occur as isolated lesions, but it could be possible to find a multiple localization involving one or more nerves. The presence of multiple schwannomas in a single patient is suggestive of a genetic predisposition to tumorigenesis and...
Merlin is encoded by the neurofibromatosis type 2 (NF2) gene and is a member of the Band 4.1 protein family. This protein acts as a linker that connects cell surface proteins to the actin cytoskeleton. Defects caused by mutations of the NF2 gene give rise to NF2 disease, which is generally characterized by the formation of bilateral vestibular schwannomas and, to a lesser extent, meningiomas an...
Neurofibromatoses (NF) are a group of genetic multiple tumor growing predisposition diseases: neurofibromatosis type 1 (NF1), neurofibromatosis type 2 (NF2) and schwannomatosis (SCH), which have in common the neural origin of tumors and cutaneous signs. They affect nearly 80 thousand of Brazilians. In recent years, the increased scientific knowledge on NF has allowed better clinical management ...
Neurofibromatosis type 2 (NF2) is an autosomal-dominant disease that results in the formation of bilateral vestibular schwannomas (VSs) and multiple meningiomas. Treatment options for NF2-associated tumors are limited, and to date, no medical therapies are FDA approved. The ideal chemotherapeutic agent would inhibit both VS and meningiomas simultaneously. The objectives of this study are (1) to...
Abstract Neurofibromatosis type 2 (NF2) predisposes affected individuals to vestibular schwannomas (VS), non-vestibular (NVS), meningiomas, and ependymomas. We developed an adaptive platform-basket trial screen multiple drugs against any of progressive NF2-related tumor. report the interim analysis first treatment arm with brigatinib, ALK inhibitor that inhibits tyrosine kinases. conducted a mu...
We cloned novel splice variants Mer150, Mer151 and Mer162 of the neurofibromatosis 2 (NF2) tumor suppressor, which demonstrate a tissue-specific and development-specific expression pattern. Isoform Mer150 is created by cryptic splicing from exon 8 to 14 and represents an N-terminal truncation of 259 residues. Mer151 is characterized by in-frame splicing out of several exons and a modified C-ter...
INTRODUCTION Patients with neurofibromatosis type 2 (NF2) develop bilateral cochleovestibular schwannomas (CVSs) that cause binaural deafness in most individuals. Hearing loss occurs in an unpredictable manner and the underlying mechanisms are not known. To gain insight into the pathophysiologic basis for hearing loss in NF2, we performed a prospective cross-sectional study of untreated ears in...
