Genetic Roots to Stuttering

Feb. 10, 2010 - The New England Journal of Medicine has published an article exploring why people stutter. The article's authors have found that three genetic mutations in the brain cells of stutterers could be the root cause. The mutations, to paraphrase Dr. Dennis Drayna, a researcher at the National Institute on Deafness and Other Communication Disorders, cause a disruption in the process of the cell that controls degradation of things that the cell does not need anymore. This discovery could lead to "more specific diagnosis and treatment".
