The mapping of the human genome and scientific discoveries regarding genetic contributions to disease hold great promise for the prevention and treatment of an array of conditions. Social workers and other professionals must keep abreast of these developments and the ethical dimensions of such progress. Familiar ethical provisions such as confidentiality, informed consent, self-determination, and social justice take on new meaning in light of innovations in genetic science. This article reviews ethical issues and practice implications emerging from advances in genetics knowledge, and it suggests mechanisms for continuing professional development and involvement in this important area.
