Update on Genetic Chorea.

ABSTRACT: Hereditary choreas are a clinically and genetically heterogeneous group of monogenic disorders in which chorea constitutes the core or an early-dominant feature. These conditions result from various genetic mutations affecting the structures and pathways involved in movement control, primarily the caudate and putamen, ultimately impairing the basal ganglia circuits involved in the regulation of movement, cognition, and behavior. This review focuses on the main forms of hereditary choreas, including Huntington's disease, neuroacanthocytosis syndromes, Huntington's disease phenocopies, benign hereditary chorea, and other less common genetic disorders presenting with chorea. We discuss the clinical, genetic, and pathophysiological features of each condition, alongside key aspects of phenomeno
