Objective: A polymorphism in the promoter region of the NPY gene at position −399 C>T was recently reported to be associated with schizophrenia in a Japanese population and with treatment refractory unipolar depression in a Swedish population. The objective of this study was to investigate potential associations between the polymorphism and three psychiatric disorders in a Danish population. Method: We investigated the occurrence of the polymorphism in patients with schizophrenia ( n = 291), unipolar depression ( n = 256) and panic disorder ( n = 142) compared with controls ( n = 716). Results: We detected the polymorphism −399 C>T at a frequency of 48% in controls. No significant differences were found between genotype or allele frequencies in controls vs. the patient groups. Conclusion: The lack of association between the −399 C>T polymorphism and schizophrenia, unipolar depression or panic disorder, respectively, suggests that the polymorphism is not involved in the etiology of these disorders in the Danish population.
