The completion of draft sequences of the human genome represented a remarkable achievement for automated DNA sequencing based on Sanger technology. However, the future requires substantial leaps in sequencing technology such that whole genome sequencing will become a standard component of biomedical research and patient care. In this review we describe current advances that are in early stages of development, but that point toward technology that will enable the onset of genomic medicine encompasses strategies for preventative medicine and intervention based on complete knowledge of an individual's genome.
