Cancer Genetics Overview (PDQ®)
[ health professional ]
Expert-reviewed information summary in which the validity and utility of genetic tests are discussed and important genetic terms are defined.

Elements of Cancer Genetics Risk Assessment and Counseling (PDQ®)
[ health professional ]

Cancer Genetics Research Resources and Information
Cancer Family Registries
Two international family registries on breast/ovarian cancer and colon cancer offer concerned individuals the opportunity to participate in research, and investigators opportunities to conduct valuable research.

Cancer Genetics Network
A national network of centers specializing in the study of inherited predisposition to cancer.

Cancer Genome Anatomy Project (CGAP)
CGAP seeks to determine the gene expression profiles of normal, precancer, and cancer cells, leading eventually to improved detection, diagnosis, and treatment for the patient.

Cancer Genetic Markers of Susceptibility
A 3-year initiative that will identify genetic alterations that make people susceptible to prostate and breast cancer.

National Human Genome Research Institute
NHGRI's mission encompasses a broad range of studies aimed at understanding the structure and function of the human genome and its role in health and disease.

Online Mendelian Inheritance in Man
This database of human genes and genetic disorders is provided by the National Center for Biotechnology Information, a division of the National Library of Medicine at the National Institutes of Health.
