Thomas D Gelehrter, MD


Dr. Gelehrter joined the faculty in 1974, and in 1977, was appointed the director of the newly-established Division of Medical Genetics in the Department of Internal Medicine. In 1987, he was appointed chair of the Department of Human Genetics, a position he held for 17 years. He became Professor Emeritus in 2007, but continues to teach medical genetics and see patients with hereditary disorders. In 2010, the Thomas D. Gelehrter Lectureship in Medical Genetics was established.

Dr.Gelehrter's research has focused on the regulation of mammalian gene expression by hormones and growth factors. His work on the multiple levels of molecular control of gene expression was continuously funded by the National Cancer Institute of the NIH, and in 1988 he received a MERIT Award from the NIH.

Dr. Gelehrter has been actively engaged in teaching his entire career. Since 1981, he has served as director of the Medical Genetics Course for medical students, and since the inception of the new curriculum in 2003, he has directed the Patients and Populations sequence, the first sequence in the M1 curriculum. In 1990, with his colleague Francis Collins, he published Principles of Medical Genetics, which was the first textbook to integrate new developments in molecular genetics with clinical genetics. It quickly became the standard textbook throughout the country, and was translated into six languages. In 2005, he received the Kaiser-Permanente Award for Excellence in Teaching in Pre-clinical Sciences, in 2009, the Lifetime Achievement Award for Excellence in Medical Education, and in 2010, the Award for Excellence in Human Genetics Education from the American Society of Human Genetics.
