title: Tardive dystonia and genetic polymorphisms of cytochrome P4502D6 and dopamine D2 and D3 receptors: a preliminary finding.
abstract: Tardive dystonia is an uncommon but intractable and distressing complication of neuroleptic treatment. It is suggested that individual predisposing vulnerability plays a major role in the development of the side effect. This study aimed to investigate relationship tardive dystonia and several genetic factors such as polymorphism of cytochrome P4502D6, and receptor polymorphisms of dopamine D(2) (TaqI A and -141C Ins/Del polymorphisms) and D(3) (Ser(9)Gly polymorphism). Nine patients with tardive dystonia were genotyped for these genetic polymorphisms. No specific genotypes or alleles were overpresented in the patients. This study suggests that these polymorphisms are not related to the development of tardive dystonia.
