Overview
The causes of glioma may include genetic factors and cytomegalovirus.
Causes
- Genetic factors
- Genetic disorders such as neurofibromatosis (type 1 and type 2) and tuberous sclerosis complex are known to predispose to their development.[1]
- DNA damages
- Epigenetic repression of DNA repair genes is often found in progression to sporadic glioblastoma. For instance, methylation of the DNA repair gene O-6-methylguanine-DNA methyltransferase(MGMT) Promoter was observed in 51.3% to 66% of glioblastoma specimens.[2][3]
- Epigenetic reductions in expression of another DNA repair protein, ERCC1, were found in an assortment of 32 gliomas.[4]
- Mutations in gliomas frequently occur in either isocitrate dehydrogenase (IDH) 1 or 2 genes. One of these mutations (mostly in IDH1) occurs in about 80% of low grade gliomas and secondary high-grade gliomas.[5]
