Clinical Molecular genetics is a laboratory-based specialty of medical genetics that focuses on the discovery of and laboratory testing for DNA mutations that underlie disease. Clinical Molecular Genetics is recognized as a primary specialty by the American Board of Medical Specialties (ABMS) [www.abms.org]. Laboratory postdoctoral fellowship training programs in this specialty are accredited by the American Board of Medical Genetics and require a minimum of 24 months of training, with a significant amount of clinical interaction as related to human genetic abnormalities. Trainees entering this specialty must hold either an M.D. or Ph.D (or their equivalent); the Ph.D. degree must either be in genetics, molecular biology, or a related field within the biological sciences. Individuals with a M.D. or Ph.D. earned outside of the United States or Canada must have their degree reviewed by the ABMG Credentials Committee prior to entering a training program. Upon successful completion of the program, clinical molecular geneticists have the skills and knowledge to function as technical supervisors of clinical laboratories as well as clinical consultants regarding laboratory diagnoses of a broad range of inherited disorders, and may in many jurisdictions be deemed qualified to direct specialty clinical molecular laboratories.
