In general developmental stuttering does have a genetic component; however, the specific gene mutation may pass over generations, the severity may be differ in family members, or the family member may be covert. These factors will vary if someone who stutters will know if it, "runs in the family" When it comes to neurogenic stuttering, it is unlikely to "run in the family".
