What causes stuttering is a question that professionals and others in the stuttering community are frequently called upon to answer. Today on StutterTalk we ask Dr. Dennis Drayna how he responds when parents ask this question. Dr. Drayna reports that a fourth stuttering gene has been found and that scientists may not be able to account for upwards of 12-20% of stuttering cases.

Dennis Drayna, Ph.D., is Senior Investigator at the National Institute on Deafness and Other Communication Disorders at the National Institutes of Health (NIH). Read more about Dr. Drayna at the NIH website here. Dr. Drayna’s other StutterTalk appearances are archived here.
