Mayo Clinic geneticist Linda Hasadsri, M.D., Ph.D., director of Mayo Clinic’s genomics laboratory, explains how universal, pan-ethnic carrier screening has become the standard of care at Mayo Clinic to detect genetic variants in an increasingly heterogenous population. Recommended by the American College of Medical Genetics and the American College of Obstetricians and Gynecologists for all expectant and prospective parents, expanded carrier screening at Mayo Clinic can detect 1,700 pathogenic variants in more than 200 genes, providing comprehensive and meaningful results.
