Abstract
We studied a variable number tandem repeat polymorphism within the dopamine transporter gene (DAT) for an association with Parkinson's disease in a Chinese population. Five alleles were detected, consisting of 6, 8, 9, 10, and 11 copies of the 40 base pair repeat sequence. The 10-copy allele was most common, accounting for 90% of alleles. There were no significant differences between the patients and the control subjects in the distribution frequencies of the alleles or genotypes. Therefore, this polymorphism is not associated with Parkinson's disease in Chinese populations.
