Description : 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). Ependymomas are rare glial tumors of the brain
and spinal cord (Yokota et al., 2003). Subependymomas are unusual tumors believed
to arise from the bipotential subependymal cell, which normally differentiates into
either ependymal cells or astrocytes. They were characterized as a distinct entity
by Scheinker (1945). They tend to be slow-growing, noninvasive, and located in the
ventricular system, septum pellucidum, cerebral aqueduct, or proximal spinal cord
(summary by Ryken et al., 1994). Gliomas are known to occur in association with several
other well-defined hereditary tumor syndromes such as mismatch repair cancer syndrome
(276300), melanoma-astrocytoma syndrome (155755), neurofibromatosis-1 (NF1; 162200)
and NF2 (101000), and tuberous sclerosis (TSC1; 191100). Familial clustering of gliomas
may occur in the absence of these tumor syndromes, however. - Genetic Heterogeneity
of Susceptibility to Glioma Germline mutations predisposing to glioma have also been
identified in the PTEN (601728) gene on chromosome 10q23.31 (GLM2; 613028) and in

Inheritance : Autosomal dominant; Somatic mutation;
