Abstract:
The melanoma genome possesses numerous recurrent chromosomal rearrangements, and embedded within this complexity are clues critical to disease pathogenesis and response to therapy. High-resolution genome-wide DNA copy number approaches, in conjunction with gene-specific mutational analyses, appear poised to define keystone molecular events, provide more accurate classification schemes, and set the stage for the design of rational therapies that may finally have an impact on survival of this deadly disease.
