Background: Comparative studies of clinical and magnetic resonance imaging findings in patients with spino-cerebellar ataxias (SCAs) have been seldom reported. Objective: To investigate clinical, genetic, and neuroradiological characteristics of SCAs in Korean kindreds. Setting: University hospital. Patients and Methods: Molecular analysis of SCA types 1, 2, 3, 6, and 7 and dentatorubral pallidoluysian atrophy and magnetic resonance imaging were performed in 67 patients with ataxia. Results: The overall prevalence of 6 types of SCAs was 54% (36 of 67 patients), irrespective of patients' family histories. The most frequent type was SCA7 (11 patients, 16%), followed by SCA3 and SCA6 (10 patients, 15% for both). Certain clinical features suggested specific gene defects, although overlap among the 6 SCA subtypes was broad: visual disturbance was noted in patients with SCA3 and SCA6, dystonia in 1 patient with SCA6, and sporadic ataxia without pigmentary retinopathy in 1 patient with SCA7. Compared with the control subjects, patients with SCAs and multisystem atrophy had a significant enlargement of the fourth ventricle and atrophy of the cerebellum (P
