2 The most common genetic abnormalities of ependymomas involve the chromosome 22 where there is the oncosuppressor gene neurofibromin 2 (NF2). NF2 mutations are primarily encountered in spinal lesions. In contrast, NF2 alterations do not seem related to tumor grade. We studied the NF2 expression through a real-time polymerase chain reaction in 25 pediatric anaplastic ependymomas. We compared the NF2 expression in neoplastic and non-neoplastic tissues, in supratentorial and infratentorial
