Abstract/OtherAbstract:
BACKGROUND: Tardive dyskinesia (TD) is a severe and potentially irreversible adverse effect of long-term antipsychotic treatment. Typical antipsychotics are commonly binding to the dopamine receptor D2 (DRD2), but the occurrence of antipsychotic-induced TD is rather delayed; therefore, the development of TD may be associated with mediators or signalling complexes behind DRD2, such as beta-arrestin 2 (ARRB2), an important mediator between DRD2 and serine-threonine protein kinase (AKT) signal cascade. METHODS: A case-control study to evaluate the association between rs1045280 (Ser280Ser) and antipsychotic-induced TD was performed amongst 381 patients (TD/non-TD = 228/153). RESULTS: There was a significant difference in the genotype distribution between TD and non-TD groups (P = 0.025); furthermore, the allelic analysis indicated that patients with T allele had increased risk of TD occurrence (OR(T) = 1.58, 95% CI = 1.14-2.19, P = 0.007). CONCLUSIONS: To the best of our knowledge, this is the first study reporting a positive association between the SNP rs1045280 and TD in schizophrenic patients.
