Molecular epidemiology of spinocerebellar ataxia type 6.
We performed a population-based clinical and molecular genetic study of spinocerebellar ataxia type 6 (SCA6) in the northeast of England. The minimum point prevalence of SCA6 was 1.59 in 100,000 (95% confidence interval [CI], 1.04-2.14), and the number of individuals who either had SCA6 or are at risk of developing SCA6 was at least 5.21 in 100,000 (95% CI, 4.31-6.10), or 1 in 19,210. Microsatellite analysis of the CACNA1A gene indicated a founder effect for SCA6 within this region.
