A recent study published by our group implicated the bromodomain containing protein 1 (BRD1) gene located at chromosome 22q13.33 with schizophrenia (SZ) and bipolar affective disorder (BPD) susceptibility and provided evidence suggesting a possible role for BRD1 in neurodevelopment. The present study reports an association analysis of BRD1 and the neighboring gene ZBED4 using a Caucasian case-control sample from Denmark and England (UK/DK sample: 490 patients with BPD, 527 patients with SZ, and 601 control individuals), and genotypes obtained from a BPD genome wide association (GWA) study of an overlapping English sample comprising 506 patients with BPD and 510 control individuals (UCL sample). In the UK/DK sample we genotyped 11 SNPs in the BRD1 region, of which six showed association with SZ (minimal single marker P-values of 0.0014), including two SNPs that previously showed association in a Scottish population [Severinsen et al. (2006); Mol Psychiatry 11(12): 1126-1138]. Haplotype analysis revealed specific risk as well as protective haplotypes with a minimal P-value of 0.0027. None of the 11 SNPs showed association with BPD. However, analyzing seven BRD1 SNPs obtained from the BPD GWA study, positive associations with BPD was observed with all markers (minimal P-value of 0.0014). The associations reported add further support for the implication of BRD1 with SZ and BPD susceptibility.

The distal long arm of chromosome 22 (22q13.3) may harbor genes implicated in schizophrenia. This is evidenced by various genetic mapping studies. BRD1 and its neighboring gene ZBED4, both located within this region, have repeatedly been found to be associated with schizophrenia in the Caucasian population. In this study, we chose seven SNPs (two BRD1 SNPs, five ZBED4 SNPs) to carry out an association study between these two genes and schizophrenia in the Chinese population. However, no significant result was obtained, which was consistent with the Japanese population. Taken together, we could conclude that BRD1 and ZBED4 might be population specific in schizophrenia and may not account for a substantial proportion of genetic risk for schizophrenia in the Asian population.
