Inside the Largest Genetic Study of Stuttering

Proud Stutter

Dr. Dillon Pruett has lived both sides of stuttering: the anxious kid rehearsing every word and the scientist searching DNA for answers. His groundbreaking research, recently published in Nature Genetics, uncovered 57 genetic hotspots tied to stuttering -- proof that our voices carry a biological story as complex as any human trait. In our conversation, Dillon shares how his personal journey shaped his path into research, what the findings reveal about stuttering’s overlap with traits like musicality and sleep, and why the goal isn’t to “fix” stuttering but to demystify it. At its heart, this episode is about turning stigma into science and science back into compassion.
