Spinocerebellar ataxia type 10 in Chinese Han

Year: 2015

Type: article

Abstract: Spinocerebellar ataxia type 10 (SCA10; OMIM #603516) is an autosomal dominant cerebellar ataxia with variably associated extracerebellar signs.(1,2) SCA10 is caused by an expanded noncoding pentanucleotide repeat in ATXN10, which normally ranges from 9 to 32 repeats(3,4); pathogenic alleles have as many as 4,500 repeats.(4) To date, SCA10 has been found exclusively on American continents. In this report, we describe a Chinese Han family with autosomal dominant cerebellar ataxia caused by an SCA10 expansion.
