Genetic Cause for Stuttering?

It appears that at least in some individuals, their stuttering may be caused by a genetic mutation, specifically a missense mutation in the N-acetylglucosamine-1-phosphate transferase gene (GNPTAB), which encodes the alpha and beta catalytic subunits of GlcNAc-phosphotransferase protein (part of the lysosomal enzyme–targeting pathway).

Other genetic mutations causing stuttering was found in the GNPTAB, GNPTG, and NAGPA genes. These genes encode enzymes that generate the mannose-6-phosphate signal, which directs a diverse group of hydrolases to the lysosome

This research was published in the February 2010 volume of New England Journal of Medicine.
