| Abstract: | Objective To study the frequency of different gene subtype of patients with spinocerebellar ataxia(SCA) in Anhui region.Methods There were 39 patients with autosomal dominant SCA from 15 families and 20 sporadic SCA patients.The trinucleotide repeat(TNR) of SCA1,SCA2,SCA3 and SCA6 gene were amplificated by PCR.The numbers of TNR were estimated by denaturing polyacrylamide gel electrophoresis and confirmed by DNA sequencing.Results The detection rate of SCA3 gene subtype was 33.33% in SCA families and the to... |
