Few studies have explored the relationship between phenotypes and genotypes of HD in Asians. We evaluated the relationship between integrated clinical and imaging phenotypes and genotypes in a Taiwanese HD cohort, enrolling 123 HD patients genetically diagnosed between August 1994 and February 2019. The clinical presentations and brain magnetic resonance imaging characteristics were analyzed from 67 patients and examined the correlation with genetic findings. Chorea was the most common initial manifestation (66.1%), especially in patients with late-onset disease (onset age > 60 years old), followed by psychiatric symptoms (25%) and cognitive impairment (14.3%). Compared to patients with adult-onset HD, the prevalence of parkinsonism was significantly higher in juvenile-onset HD patients (onset age < 20 years old, p =.007). Disease burden, which was measured by CAG repeats and age, was significantly associated with atrophy in caudate nucleus (p =.004), followed by putamen (p =.029), nucleus accumbens (p =.002), thalamus (p =.003), and total cortical volume (p =.001) after correcting for total intracranial volume. Our findings, that provided the first series of Taiwanese HD patients, delineated the clinical, radiological, and genetic characteristics in Asian HD patients. ? 2020 Wiley Periodicals LLC.[SDGs]SDG3adult; Article; brain atrophy; brain size; caudate nucleus; cognitive defect; cohort analysis; disease association; disease burden; female; genetic analysis; genetic correlation; genotype; human; Huntington chorea; late onset disorder; major clinical study; male; middle aged; nuclear magnetic resonance imaging; nucleus accumbens; parkinsonism; phenotype; prevalence; priority journal; putamen; Taiwanese; thalamus; Asian continental ancestry group; atrophy; disease exacerbation; ethnology; genetics; Huntington chorea; onset age; pathology; procedures; Taiwan; trinucleotide repeat; Adult; Age of Onset; Asian Continental Ancestry Group; Atrophy; Caudate Nucleus; Disease Progression; Female; Genotype; Humans; Huntington Disease; Magnetic Resonance Imaging; Male; Middle Aged; Nucleus Accumbens; Phenotype; Taiwan; Trinucleotide Repeatsjournal article10.1002/ajmg.b.32810326433042-s2.0-85087702748
