Dysbindin gene (DTNBP1) has been associated with schizophrenia, but literature findings are inconsistent, and further analyses are required. This study is aimed to investigate if a set of DTNBP1 variations might influence clinic psychotic phenotype or treatment response in a sample of 240 Korean schizophrenic in-patients. Four variants have been selected (rs3213207; rs1011313; rs16876759; rs2619522) on the basis of previous findings of association with schizophrenia, bipolar disorder and antidepressant response. Single marker analysis gave marginal results. Haplotype analysis identified a significant association between A-A (rs3213207(A/G), rs1011313(A/G)) haplotype and lower PANSS total and positive scores at baseline (p = 0.01; 0.02) and at discharge (p = 0.008; 0.005). Covariate analysis revealed a more stable significant association between A-A haplotype and baseline scores. These results suggest a protective effect of A-A haplotype on psychotic positive symptoms at baseline.
