Huntington Disease

Huntington disease is caused by HTT CAG repeat expansion (≥36 copies); autosomal dominant; choreoathetosis, cognitive decline, and psychiatric disturbance onset in the 4th-5th decade; disease-modifying HTT-lowering therapies (ASOs, siRNA) are in Phase 3 clinical trials.

Also known as: Huntington disease, HD, Huntington's disease, HTT CAG expansion, huntingtin disease, chorea HD, polyQ neurodegeneration, HD neurodegeneration, CAG repeat disease, HTT repeat expansion
