There is growing evidence to support the hypothesis that there is a neurodevelopmental component to the late-onset neurodegeneration occurring in the brain of huntingtin gene (HTT gene) mutation carriers, and that this increased susceptibility to brain cell death begins during childhood. Experts discuss the evidence that the HTT gene mutation affects brain and body growth based on a unique study of children at risk for HD, the Kids-HD study, in a review paper and accompanying research article published in the Journal of Huntington’s Disease.
