If you are not a biologist or MD, and want to see where the application of genomics to medicine is going, try Brown's book. In clear language, he and other writers explain the key ideas and promises in this field. Like what can be done with massive genomic databases, by aiding the search for inherited diseases, and isolating these to certain places in the DNA.
One chapter looks at gene therapy. Currently, still mostly speculative. Much remains to be done to make it viable for many people. But this chapter is perhaps the most far reaching, if its potential can be fully realised. Related to this is another chapter about proteomics, which is another buzzword. We see that protein structures are another field, closely related, that also holds big promises for understanding and treatments.
