title: A study of familial stuttering.
abstract: Here we study 13 families with stuttering. Of the 13 families, 9 were persistent stutterers and 4 were recovered stutterers. In the 9 families with persistent stuttering, 24 were male and 10 were females. Of the 4 families with recovered stutterers, 17 were male and 3 were female. Of the 17 males, 12 were persistent stutterers and 5 recovered after adolescence. All females were recovered stutterers. We conclude with a short discussion of recent molecular studies.
