Genetic? **NO!** There appears to be genetic factors that can contribute to stuttering, but no one is born with a stutter. Speech is learned. It's a developmental process. Genetics can influence ones development in this arena, but there isn't any 'stuttering gene', per se. I'd caution people to avoid labeling stuttering as genetic or a disability. Doing so implies permanence. The majority of stutterers can achieve fluency. It requires professional assistance and no small degree of determination. Many stutterers, and their families, get really lousy advice early on. In my case, the two things that delayed my fluency for 20+ years were :"He'll grow out of it", and the failure to see a professional therapist. The public school assigned me a speech therapist. Public school therapists (speech, OT, PT, etc.) are good people with the best intentions, but they are no substitute for professional therapy. Early intervention will yield the best results.
