Multicolor fluorescencein situhybridization in clinical cytogenetic diagnostics

摘要

Multicolor fluorescencein situhybridization is a technology that has vastly expanded the diagnostic repertoire of the clinical cytogenetics laboratory. The limitations of conventional chromosome banding analysis can often be overcome by the high sensitivity and specificity of multicolor fluorescencein situhybridization tests. This article reviews the latest multicolor fluorescencein situhybridization tests (including multiplex fluorescencein situhybridization, spectral karyotyping, cross-species color banding, and comparative genomic hybridization) that are currently limited to a few select clinical cytogenetic laboratories, but may soon have more dominant roles in clinical cytogenetic practice.
