Annotated Bibliography: Introduction The increased understanding of genetics, largely the result of the completion of the Human Genome Project, has helped change the face of modern medicine. Genetic testing of an individual can not only help identify current diseases and disorders, but also help suggest treatment modalities and identify potential future illnesses. For example, patients with a family history of breast cancer can be tested for the breast-cancer gene, and, if positive, decide whether to pursue preventative therapies, such as pre-cancerous mastectomies. However, it is critical for healthcare workers to understand all of the ramifications of genetic testing so that they can answer patient questions about those tests. For example, if a genetic test can identify a disorder, but there is no preventative care or treatment for that disorder, will that knowledge help or harm the individual? Summaries Lea, D.H. (2009). Basic genetics and genomics: A primer for nurses. The Online Journal of Issues in Nursing, 14(2). doi: 10.3912/OJIN.Vol14No02PPT01. Lea examines the implications of the completion of the Human Genome Project on the provision of personalized healthcare services to patients. The article provides a good overview of basic genetics, so that it can serve as an introduction to the subject for nurses who are unfamiliar with genetics. After reviewing the basic science, Lea concludes that genetics/genomics are a routine part of screening,
