Spinocerebellar Ataxia Type 6 and Japanese Immigration to Brazil.

This article discusses the prevalence of spinocerebellar ataxia type 6 (SCA6) in Japanese immigrants in Brazil. The authors compare the frequency of SCA6 in Japan and Brazil, finding that it is relatively uncommon in Brazil compared to other subtypes of SCA. They also note that all of the SCA6 patients in their study had Japanese ancestry. The authors suggest that genetic diseases should be considered and investigated in individuals with Japanese ancestry, and that this guidance should be applied in other countries as well.
