Schizophrenia patients show alterations in the synaptic connectivity. However, it remains unknown whether antipsychotic response may be altered depending on the synaptic connectivity. We tested this association using polymorphisms in the neurexin 1 gene (NRXN1). Large NRXN1 deletions have also been associated with schizophrenia. We genotyped four variants in 140 schizophrenia patients assessed prospectively for clozapine response after 6 months. We observed a trend toward association of clozapine response with the rs12467557 (permuted p = 0.051). These results should be read with caution before independent replication.
