Objective: To evaluate the impact of mHTT on the developmental trajectories of cortical thickness and surface area. Methods: Children and adolescents (6\u201318 years) participated in the KidsHD study. mHTT carrier status was determined for research purposes only to classify participants as gene expanded (GE) and gene non-expanded (GNE). Cortical features were extracted from 3T neuroimaging using FreeSurfer. Nonlinear mixed effects models were conducted to determine if age, group, and CAG repeat were associated with cortical morphometry. Results: Age-related changes in cortical morphometry were similar across groups. Expanded CAG repeat was not significantly associated with cortical features. Conclusion: While striatal development is markedly different in GE and GNE, developmental change of the cortex appears grossly normal among child and adolescent carrier of mHTT.<\/jats:p>","DOI":"10.3233\/jhd-210512","type":"journal-article","created":{"date-parts":[[2022,3,8]],"date-time":"2022-03-08T13:56:48Z","timestamp":1646747808000},"page":"173-178","source":"Crossref","is-referenced-by-count":5,"title":["Cortical
