DEFINITION
Huntington’s disease is an autosomal-dominant, progressive neurodegenerative disorder with a distinct phenotype, including chorea and dystonia, incoordination, cognitive decline, and behavioral difficulties. Typically, the onset of symptoms is in middle-age after affected individuals have had children, but the disorder can manifest at any time between infancy and senescence. The mutant protein in Huntington’s disease—huntingtin—results from an expanded CAG repeat leading to a polyglutamine strand of variable length at the N-terminus.
