Researchers have obtained new evidence that at least some persistent stuttering is caused by mutations in a gene governing not speech, but a metabolic pathway involved in recycling old cell parts. Beyond a simple association, the study provides the first evidence that mutations affecting cellular recycling centers called lysosomes actually play a role in causing some people to stutter.
