Fluency Disorders in Genetic Syndromes

John Van Borsel

Genetic syndromes are often associated with mental retardation and the prevalence of stuttering in the mentally retarded is generally assumed to be high. Yet, detailed accounts on the occurrence and nature of fluency disorders in individuals with genetic syndromes are scarce. This presentation reviews the available literature on fluency disorders in a number of syndromes. Included are Down Syndrome, Fragile X Syndrome, Prader-Willi Syndrome, Tourette Syndrome, neurofibromatosis type I, and Turner Syndrome.
