Abstract
The present invention provides an isolated DNA sequence of the short arm of chromosome 6 which is located within the autosomal dominant spinocerebellar ataxia type 1 gene. This isolated DNA sequence is preferably located within a 3.36 kb EcoRI fragment, i.e., an EcoRI fragment containing about 3360 base pairs, of the SCA1 gene. The isolated sequence preferably contains a CAG repeat region. The number of CAG trinucleotide repeats (n) is.ltoreq.36, preferably n=19-36, for normal individuals. For an affected individual n>36, preferably n.gtoreq.43.
