Book excerpt: Increasingly, genomic-based approaches and resources are redefining our categorization of disease, leading to new approaches to prevention and therapy. As nurses traditionally practice patient-oriented care, they will undoubtedly play a key role in both developing and applying the aspects of genomic health care. Nursing Care in the Genomic Era: A Case Based Approach is designed to provide nurses with up-to-date and accessible information on this powerful new approach to understanding, preventing, and treating disease.
