Background: The adenosine A2A receptor forms a heteromeric complex with the striatal dopamine D2 receptor. We examined whether a specific polymorphism in adenosine A2A receptor (2592 C/Tins) is associated with tardive dyskinesia.
Methods: Tardive dyskinesia was assessed cross-sectionally in 146 Caucasian psychiatric inpatients from Siberia.
Results: Between-group comparisons of genotypic or allelic frequencies showed no statistically significant difference. Logistic regression analysis with the occurrence of tardive dyskinesia as dependent variable showed no significant association with age, duration of illness, gender, and genotype.
Conclusion: The interaction between the A2A and D2 receptors seems not involved in the development of tardive dyskinesia.
