Lack of impact of undergraduate genetic courses on the teaching of medical genetics.

The impact of undergraduate genetic courses on the academic performance of first-year medical students in the medical genetics course at the University of Pittsburgh School of Medicine was evaluated over a period of 9 years. Comparisons were made between medical students who had taken a formal undergraduate course in genetics and those who had not. Little if any differences were found in the academic performance in the medical genetics course between these two groups of students. Perhaps the design of undergraduate courses in genetics should be re-evaluated to give more depth to the medical student's preparation for appreciating the significance of genetics in normal and abnormal human variation.
