Overview
Common risk factors in the development of ependymoma are certain hereditary diseases (neurofibromatosis type II and Turcot syndrome), over-expression of kinetochore proteins, and down-regulation of metallothioneins.
Risk Factors
- Children with certain hereditary diseases, such as neurofibromatosis type II (NF2), Turcot syndrome B, and MEN1 syndrome, have been found to be more frequently afflicted with ependymal tumors.
- Increased occurrence of chromosome 1q and proteins such as tenascin C and epidermal growth factor are associated with increased risk for developing ependymal tumors.
- ERBB2, ERBB4, and human telomerase reverse transcriptase TERT gene expression promote tumor cell proliferation, contributing to aggressive tumor behavior.
- High expression of epidermal growth factor receptor EGFR correlates with unfavorable outcome.[1]
- Over-expression of kinetochore proteins and down-regulation of metallothioneins are associated with recurrence of ependymomas.[2]
