title: Homozygous deletions of the MTS1 gene are rare in non-astrocytic brain tumors.
abstract: Several studies support a role for the multiple tumor suppressor gene (MTS1) in the malignant progression of different tumor types. In this study we have examined the status of the MTS1 gene in a variety of non-astrocytic tumors of the central nervous system. It was not possible, using multiplex PCR with primers for MTS1 and D9S196, a chromosome 9q marker, to demonstrate deletions of MTS1 in 59 primary non-astrocytic tumors. Two out of 5 (40%) secondary tumors showed evidence of homozygous deletion of MTS1. The results obtained here for primary non-astrocytic tumors contrast with those previously described for astrocytic tumors where a high frequency of deletions of MTS1 was associated with tumor progression.
