Mayo Clinic's approach

  • Teamwork. In Mayo Clinic's Department of Clinical Genomics, medical geneticists and certified genetic counselors work together as a team, with other professionals as needed, to evaluate any type of genetic condition and coordinate a wide array of tests and procedures.
  • Comprehensive services. The Department of Clinical Genomics provides diagnostic workup of rare and inherited conditions and genetics evaluation of hereditary cancer syndromes, takes a comprehensive family history, educates patients and families about familial diseases, and offers counseling for family members to improve understanding of how a genetic disorder may affect them.
  • Advanced technology. The Department of Clinical Genomics provides access to the latest genomic testing techniques, when medically appropriate and on a case-by-case basis.
  • Research. Mayo Clinic is recognized for outstanding contributions to research in genetics and genomics. Patients have opportunities to participate in genetic research studies to improve overall patient care. Mayo's Center for Individualized Medicine is involved in translating the latest scientific advances to clinical care.
