<unk> s are similar in nature to the adult form of<unk>  in that they are thought to arise from radial glial cells lining the ventricular system. However, they differ from adult<unk> s in which genes and chromosomes are most often affected, the region of the brain they are most frequently found in, and the prognosis of the patients. Children with certain hereditary diseases, such as neurofibromatosis type II (NF2), have been found to be more frequently afflicted with this class of tumors, but a firm genetic link remains to be established. Symptoms associated with the development of<unk> s are varied, much like symptoms for a number of other<unk>  brain tumors including vomiting, headache, irritability, lethargy, and changes in gait. Although younger children and children with invasive tumor types generally experience less favorable outcomes, total removal of the tumors is the most conspicuous prognostic factor for both survival and relapse.
