摘要
ObjectiveTardive dyskinesia (TD) is a motor side effect that may develop after long-term antipsychotic treatment. Schizophrenia has recently been associated with the Neurexin-1 (NRXN1) gene that codes for a cell adhesion molecule in synaptic communication. MethodsThis study examined five NRXN1 single-nucleotide polymorphisms (SNPs) for possible association with the occurrence and severity of TD in 178 schizophrenia patients of European ancestry. ResultsWe did not find these SNPs to be significantly associated with TD. ConclusionsMore research is needed with additional SNPs and in bigger samples before we can completely rule out the role of NRXN1 in TD.
