Individual genomes vary, not only in sequence, but in both their structural organization and in the number of sequence copies they contain. The technology now exists to understand the mechanisms by which genomes diverge, so we can investigate the consequences of copy number variation for gene expression and clinical phenotypes. This month (September), Nature Genetics presents a Focus of articles published in Nature and Nature Genetics, free to read online, on copy number variation, which highlights the complementary roles of paired-end sequencing and oligonucleotide array technology in research discovery.
