Chromosomal imbalances detected by array comparative genomic hybridization in human oligodendrogliomas and mixed oligoastrocytomas

Loss of heterozygosity and fluorescence in situ hybridization (FISH) studies have shown that deletions of 1p and 19q are highly prevalent in oligodendroglioma. However, these tumors have not been comprehensively screened for other alterations in chromosomal dosage. In this study, we used array‐based...
