Abstract

Gliomas are tumors of the central nervous system that may be inherited in some patients. The gene(s) responsible for the clustering of gliomas in families have not yet been identified. Molecular studies of sporadic high-grade gliomas have revealed mutations or deletions of the genes encoding the protein kinase inhibitors p16(INK4A) and p15(INK4B) in a large proportion of tumors. Moreover, those tumors without deletions frequently display gene amplification and/or overexpression of mRNA encoding the protein kinase cdk4. We hypothesized that germ-line mutations in the p16(INK4A), p15(INK4B), or CDK4 genes might contribute to some cases B familial gliomas. To address this issue, we analyzed 36 kindreds with a predisposition to glial tumors. Genomic DNA from index members of these families was screened by PCR-single-strand conformational polymorphism analysis. We did not detect any functional mutations in the p16(INK4A) p15(INK4B), or CDK4 genes, although two individuals did have a previously described A140T polymorphism in p16(INK4A). Thus, despite the association between the sporadic forms of high-grade glioma and abnormalities of p16(INK4A), p15(INK4B), or CDK4, we found no evidence that germ-line mutations in the coding region of these three genes predispose to inherited glial tumors.
