Abstract

Genes encoding proteins involved in dopaminergic transmission are potential candidate genes for the induction of somnolence in Parkinson's disease (PD) because dopaminergic agents have been shown to be associated with sudden onset of sleep (SOS) in PD. We conducted an association study on dopamine D2, D3, and D4 receptor gene polymorphisms comparing 137 PD patients with SOS and 137 PD patients without SOS matched according to drug therapy, disease duration, sex, and age. Our results show a significant association between the dopamine D2 receptor gene polymorphism Taq IA and SOS in PD. No significant association between two other investigated polymorphisms and the phenomenon of “sleep attacks” in PD was observed. © 2004 Movement Disorder Society

Sleep attacks are a common yet only recently recognized phenomenon in patients with Parkinson's disease (PD). Initially reported to occur only with particular dopamine agonists, sleep attacks have been observed with all dopaminergic drugs. [1][2][3] In the majority of affected patients, sleep attack

## Abstract The presynaptic dopamine transporter in nigral dopaminergic neurons confers susceptibility to the cytotoxic effects of the neurotoxic metabolite of 1‐methy1‐4‐phenyl‐1,2,3,6‐tetrahydropyridine. Polymorphisms in the dopamine transporter might influence the susceptibility to such toxins.

We studied a polymorphism in the dopamine transporter (DAT) gene in 236 Japanese patients with Parkinson's disease (PD) and compared the results with 220 controls. The 1215A/G genotype of the DAT gene was significantly different between PD patients and controls, suggesting a possible involvement of
