Additional Information:

Description: (OMIM) Gliomas are central nervous system neoplasms derived from glial cells and comprise astrocytomas, glioblastoma multiforme, oligodendrogliomas, ependymomas, and subependymomas. Glial cells can show various degrees of differentiation even within the same tumor (summary by Kyritsis et al., 2010). ...
Diagnosis OMIM Marie et al. (2001) found that OLIG2 (606386) expression was upregulated in neoplastic oligodendrocytes, but not in neoplastic astrocytes or in other brain tumor cells, and suggested its use as a specific marker in the diagnosis of oligodendroglial ...
Molecular genetics OMIM Kyritsis et al. (1994) identified germline mutations in the TP53 gene (see, e.g., 191170.0042) in 6 of 19 patients with multifocal glioma, all of whom had a family history of cancer. In addition, germline TP53 mutations were found ...
