Dear Joseph,
There is a great deal of evidence supporting the view that at least some stuttering is hereditary. This evidence consists of studies of twins, studies of adopted children, and studies of families such as yours, in which a large number of family members are affected with stuttering. In addition, several new studies have gone a step further, and have produced evidence for the location of specific genes that appear to be at work in some of these instances. We have recently completed such a study here at the National Institutes of Health in Bethesda, Maryland, and have strong evidence for the location of one such gene. We are interested in studying other families with a distinctive pattern of stuttering. Your family would be of great interest to us. If you and other family members are interested in participating in our research study, please contact us by e-mail at: drayna@nidcd.nih.gov , or by mail at: NIDCD, 5 Research Court, Room 2B-46, Rockville, MD 20850 USA. Thank you for your interest in the genetics of stuttering.
