Therapeutic horizons--the human genome.

The sequence of many genes has been conserved during evolution, offering insights into gene function and new opportunities for research in pharmacology and drug development. The many ethical issues surrounding genetics have the potent tial to halt the genomic revolution unless society strives to understand and resolve these issues. Advances in pharmacogenomics hold significant promise for improved health care, such as by enabling clinicians to select the optimal medications and dosages for individual patients.
