Division of Human Genetics

Our team of medical geneticists, including physicians, laboratory specialists and genetic counselors, provides a full range of genetic services to patients of all ages, their families and health care providers. Services are available to patients and families when a genetic cause or contribution to medical or neurodevelopmental problems is known or suspected, including inborn errors of metabolism, chromosomal disorders, genetic syndromes and genetic contribution to common/complex disease that may present at any age. We provide genetic diagnostic evaluation, clinical monitoring, treatment and management, and genetic counseling in both the inpatient and outpatient settings. Board-certified clinical geneticists and laboratory geneticists are on call at all times.

The Division faculty members serve as national leaders in education in genetics and genetic professional organizations. Currently, Miriam Blitzer, PhD, is the Executive Director of the American Board of Medical Genetics and 2011-2012 President of the Professors of Human Genetics. Carol Greene, MD, is President of the Society for Inherited Metabolic Disorders (2011-2013), and Shannan Dixon, MS, CGC, is currently serving as treasurer of the Association of Genetic Counseling Program Directors and is on the board of directors of the National Society of Genetic Counselors. Our faculty and trainees are active in clinical research in medical genetics and serve on committees of professional organizations.
