In this 72-minute DVD, Dennis Drayna, Ph.D., of the National Institute on Deafness and Other Communication Disorders, provides an update on recent research findings in the genetics of stuttering. This video describes the evidence for genetic factors in stuttering and the genes discovered to date. It discusses the function of these genes and what they tell us about the underlying causes of stuttering. It also discusses efforts to create an animal model for stuttering by putting human stuttering mutations into mice and analyzing their ultrasonic vocalizations.
