Genome-wide linkage and association analyses were conducted to identify genetic determinants of stuttering in a founder population in which 48 individuals affected with stuttering are connected in a single 232-person genealogy. A novel approach was devised to account for all necessary relationships to enable multipoint linkage analysis. Regions…

Immediate and extended families of 66 stuttering children were investigated to determine frequencies of persistent and recovered stuttering. Recovery was far more common among females than males. Recovery or persistence was found to be transmitted, but the two types are not genetically independent, consistent with hypothesis that both forms share…

This article reviews and critiques the research on possible genetic factors in stuttering. The failure to consider epidemiologic factors is thought to have biased previous research, but recent data provide evidence that spontaneous recovery and chronicity are influenced by genetic factors. Findings support previous conclusions about combined…

Stuttering has been considered a heritable disorder since the 1930s. There have been different models of transmission that have been proposed most involving a polygenic component with or without a major locus. In spite of these models, the characteristics being transmitted are not known. This study used two different tasks--a tapping task that is…

This is one of few professional books that addresses the subject of stuttering in young children. This is surprising considering that most cases of stuttering begin in the preschool years and that the prevalence of the disorder in very young children is higher than in any other age group. This excellent and informative text is written for…
