Did Neanderthals Stutter? – An Update on Genetic Stuttering Research with Dr. Dennis Drayna from the NIH (378)
Dennis Drayna, Ph.D., Senior Investigator at the National Institute on Deafness and Other Communication Disorders at the National Institutes of Health, joins Peter Reitzes to update listeners on genetic research pertaining to stuttering.
Dr. Drayna discusses current genetic research on stuttering, gene mutations that lead stuttering and speculates as to why or how such mutations cause stuttering. Dr. Drayna is asked about stuttering severity, recovery, stuttering predisposition, gene patent law currently being heard by the Supreme Court of the United States, stuttering as a motor/speech problem, the possibility of individualized gene mutations or variants that may cause stuttering, genetic research on stuttering using mice, gene expression, the possibility of stuttering in early humans and neanderthals and much more.
Dr. Drayna appeared on StutterTalk in 2010 when his research team identified mutations in three genes as a source of stuttering in almost 9% of the volunteers studied. Listen here.
