A total of 252 age- and gender-matched healthy subjects were recruited as control group. Their blood samples were collected. Genotyping of Ser9Gly polymorphism was carried out using polymerase chain reaction-restriction fragment length polymorphism. Results No statistical difference was identified in Ser9Gly polymorphism among three groups in both gene types and allel (χ2 = 3.095, χ2 = 2.627, P > 0.05). Conclusion Ser9Gly polymorphism in DRD3 gene may not be a susceptible factor for depression in PD in China.
