Abstract

The transition from low grade astrocytoma to glioblastoma multiforme is almost always accompanied by the loss of genetic markers from chromosome 10. Recently two genes, PTEN/MMAC1/TEP1 and DMBT, have been isolated from chromosome 10q. We have analysed these two genes for mutations in 21 primary glioblastomas. An exon by exon screen of the PTEN gene using SSCP failed to identify any mutations in this tumour series. In contrast, 38% of tumours showed intragenic homozygous deletions in the DMBT gene. The fact that the majority of gliomas do not carry mutations in either of these genes suggests that there may still be other genes on chromosome 10 which are important in the development of glioblastoma multiforme.
