Abstract
Sixteen patients from nine Chinese families with spinocerebellar ataxia type 2 (SCA2) were heterozygous for a CAG repeat expansion in the SCA2 gene containing 37 to 56 repeats, whereas the normal alleles carried 14 to 28 repeats. One or two CAA triplets within the CAG tract were seen in normal, but not in the expanded alleles. A strong inverse correlation was established between the number of CAG repeats and the age of disease onset. SCA2 accounted for 12% of the known Chinese families with spinocerebellar ataxia.
