Abstract

Schizophrenia and bipolar disorder share common genetic background. Several loci such as 18p11, 13q32, and 22q11-13 were commonly linked with these diseases. Since mitochondrial dysfunction has been suggested in both of these disorders, NDUFV2 at 18p11, encoding a subunit of the complex I, NADH ubiquinone oxidoreductase, is a candidate gene for these diseases. We previously reported that single nucleotide polymorphisms (SNPs) in the upstream region of NDUFV2 were associated with bipolar disorder in Japanese. The association of haplotype consisting of two SNPs, -3542G > A and -602G > A, with bipolar disorder was also seen both in Japanese and the National Institute of Mental Health Pedigrees trios. In this study, 2 polymorphisms, -3542G > A and -602G > A, were investigated in 229 schizophrenic patients as compared with controls. Individual genotypes were not associated with schizophrenia. However, the haplotype consisting of these two SNPs were significantly associated with schizophrenia. These results suggested that inter-individual variation of the genomic sequence of the promoter region of NDUFV2 might be a genetic risk factor common to bipolar disorder and schizophrenia.
