Abstract

Recent study of linkage disequilibrium mapping showed one of the trace amine receptor (TRAR) genes, TRAR4, was associated with schizophrenia. We conducted a replication study of TRAR4 with schizophrenia in Japanese patients. We used two large independent sets of samples in a first-set analysis (cases = 405, controls = 401) and second-set analysis (cases = 503, controls = 440). In the first-set analysis, one Marker (Marker5) showed a significant association, but this significance was not seen in the second-set analysis. Our results indicate that TRAR4 may not play a major role in Japanese schizophrenia patients, and that it is important to examine the possibility of false positives in genetic association analysis.
