BACKGROUND Recent genome-wide association studies (GWASs) investigating bipolar disorder (BD) have detected a number of susceptibility genes. These studies have also provided novel insight into shared genetic components between BD and schizophrenia (SCZ), two major psychotic disorders. To examine the replication of the risk variants for BD and the(More)
Parthenocarpy, the ability to set fruits without pollination, is a useful trait for setting fruit under unfavorable conditions. To identify the loci controlling parthenocarpy in eggplant (Solanum melongena L.), we constructed linkage maps by using co-dominant simple sequence repeat and single nucleotide polymorphism markers in F2 populations derived from(More)
BACKGROUND Clozapine-induced agranulocytosis (CIA)/clozapine-induced granulocytopenia (CIG) (CIAG) is a life-threatening event for schizophrenic subjects treated with clozapine. METHODS To examine the genetic factor for CIAG, a genome-wide pharmacogenomic analysis was conducted using 50 subjects with CIAG and 2905 control subjects. RESULTS We identified(More)
This is the first report on genetic mapping of a resistance locus against Fusarium wilt caused by the plant pathogen Fusarium oxysporum f. sp. melongenae in cultivated eggplant. Fusarium wilt, caused by the plant pathogen Fusarium oxysporum f. sp. melongenae, is a major soil-borne disease threatening stable production in eggplant (Solanum melongena).(More)
Recent genome-wide association studies (GWASs) of schizophrenia (SCZ) identified several susceptibility genes and suggested shared genetic components between SCZ and bipolar disorder (BD). We conducted a genetic association study of single nucleotide polymorphisms (SNPs) selected according to previous SCZ GWAS targeting psychotic disorders (SCZ and BD) in(More)
Rare inherited variations in multiplex families with schizophrenia are suggested to play a role in the genetic etiology of schizophrenia. To further investigate the role of rare inherited variations, we performed whole-exome sequencing (WES) in three families, each with two affected siblings. We also performed a three-stage follow-up case-control study in a(More)
Rare genomic variations inherited in multiplex schizophrenia families are suggested to play a role in the genetic etiology of the disease. To identify rare variations with large effects on the risk of developing schizophrenia, we performed whole-exome sequencing (WES) in two affected and one unaffected individual of a multiplex family with 10 affected(More)
AIM Pegylated interferon (PegIFN) therapies for hepatitis C virus (HCV) infection often induce a depressive state. This study aimed to identify the risk factors for and clinical characteristics of PegIFN-induced depressive state. METHODS Sixty-nine subjects with HCV who received PegIFN therapy were enrolled. Before beginning therapy, all subjects were(More)
