Genomic DNA-chip hybridization in t(11;14)-positive mantle cell lymphomas shows a high frequency of aberrations and allows a refined characterization of consensus regions

Abstract excerpt

Tumor samples of 53 patients with t(11;14)-positive mantle cell lymphomas (MCLs) were analyzed by matrix-based comparative genomic hybridization (matrix-CGH) using a dedicated DNA array. In 49 cases, genomic aberrations were identified. In comparison to chromosomal CGH, a 50% higher number of aberrations was found and the high specificity of matrix-CGH was demonstrated by fluorescence in situ hybridization (FISH)...
