Over the past decade, science has made historic progress in identifying the genetic origins of human development and functioning. From Down syndrome to sickle cell anemia, hereditary cancers to neurologic conditions, genetic tests now exist for dozens of human conditions. Research on the human genome continues apace, and the already considerable demand for genetic counseling services can only intensify as new genetic tests become available. The first book devoted exclusively to the principles and practice of genetic counseling, A Guide to Genetic Counseling prepares genetic counselors and health care providers to meet that demand. Reflecting the experiences and expertise of more than a dozen genetic counseling, medical, and legal professionals, this book defines the theory, goals, and core competencies associated with the practice of genetic counseling. Combining clear step-by-step guidelines with many fascinating and instructive case studies, it tutors readers in the gamut of skills, procedures, and ethical, legal, and psychosocial considerations integral to the genetic counseling process, including: Obtaining family histories and interviewing clients Performing medical genetic evaluations Patient education and psychosocial counseling Developing multicultural skills Case preparation and management Medical documentation Ethical and legal conduct Making the most of computer-based resources Professional development. A Guide to Genetic Counseling belongs on the syllabi of all medical and human genetics and genetics counseling certification programs. It is an indispensable working resource for professional genetic counselors and all health care providers charged with educating patients in genetic diseases.
