Abstract

We identified two polymorphisms out of all coding regions of the dopamine transporter gene. One existed in exon 9 (1215A/G) and another in exon 15 (1898T/C). The 1215G was significantly less frequent among patients with Parkinson's disease than the controls. Although the polymorphism caused no amino acid substitution, we concluded that it was associated with decreasing the susceptibility to Parkinson's disease through mechanisms other than the protein function of dopamine transporter.
