The majority of human cancers as well as many developmental abnormalities harbour chromosomal imbalances, many of which result in the gain and/or loss of genomic material. Conventional comparative genomic hybridisation (CGH) has been used extensively to map DNA copy number changes to chromosomal positions. The introduction of microarray CGH provided a powerful tool to precisely detect and quantify genomic aberrations and map these directly onto the sequence of the human genome. In the past several years, a number of different approaches towards array-based CGH have been undertaken. This paper reviews these approaches and presents some of the recently-developed applications of this new technology in both research and clinical settings.
