The lack of a role for p53 in astrocytomas in pediatric patients.

Mutations in the p53 gene, which codes for a cell division regulatory protein, have been identified in approximately one-third of adult astrocytomas. We evaluated 35 astrocytic tumors (17 pilocytic, 4 diffuse low grade, 12 anaplastic, and 2 glioblastoma) in pediatric patients for p53 mutations, using polymerase chain reaction-single-stranded conformation polymorphism analysis as a screening technique....
