Systemic lupus erythematosus (SLE) is an autoimmune disease that causes multiple organ damage. Although recent genome-wide association studies (GWAS) have contributed to discovery of SLE susceptibility genes, few studies has been performed in Asian populations. Here, we report a GWAS for SLE examining 891 SLE cases and 3,384 controls and multi-stage(More)
In order to investigate the contribution of genetic variation in the human dopamine receptor D4 gene (DRD4) to the risk of developing schizophrenia, we carried out a genetic analysis of 27 polymorphisms in 216 schizophrenic patients and 243 healthy controls from the Kyushu region of Japan. Twenty-two single nucleotide polymorphisms (SNPs) and five(More)
Non-small-cell lung cancer harboring epidermal growth factor receptor (EGFR) mutations attains a meaningful response to EGFR-tyrosine kinase inhibitors (TKIs). However, acquired resistance to EGFR-TKIs could affect long-term outcome in almost all patients. To identify the potential mechanisms of resistance, we established cell lines resistant to EGFR-TKIs(More)
OBJECTIVE Identification of the genes responsible for systemic lupus erythematosus (SLE). METHODS All the exons and putative promoter regions of 53 candidate genes (TNFRSF6/Fas, TNFSF6/FasL, Fli1, TNFSF10/TRAIL, TNFSF12/TWEAK, Bcl-2, PTEN, FADD, TRADD, CDKN1A, TNFRSF1A/TNFR1, TNFRSF4/OX40, TNFSF4/OX40L, TNFSF5/CD40L, TNFSF13B/BAFF, ICOS, CTLA4, CD28, FYN,(More)
PURPOSE To identify possible mutations in known candidate genes in patients with autosomal recessive (ar) and simplex retinitis pigmentosa (RP), by using an established strategy of flexible, multiplexed, microsatellite-based homozygosity mapping. METHODS A total of 78 microsatellite markers corresponding to 16 genes known to be responsible for arRP were(More)
OBJECTIVE In order to study the role of the p53 tumour suppressor gene in the proliferation of rheumatoid arthritis (RA) synovium, we analysed the mutation of p53 in the synovial fibroblast-like type B synoviocyte from RA patients. METHODS Synovial fibroblast-like type B synoviocytes were prepared from the synovial tissues from nine Japanese patients with(More)
PURPOSE To search for mutations in the Norrie disease gene (NDP) in Japanese patients with familial exudative vitreoretinopathy (FEVR) and Norrie disease (ND) and to delineate the mutation-associated clinical features. METHODS Direct sequencing after polymerase chain reaction of all exons of the NDP gene was performed on blood collected from 62 probands(More)
The haplotype map constructed by the HapMap Project is a valuable resource in the genetic studies of disease genes, population structure, and evolution. In the Project, Caucasian and African haplotypes are fairly accurately inferred, based mainly on the rules of Mendelian inheritance using the genotypes of trios. However, the Asian haplotypes are inferred(More)
We have employed a laser-capture microdissection technique and single-nucleotide polymorphism arrays to characterize genomic alterations associated with the development of glioblastoma multiforme (GBM). Combined analysis of loss of heterozygosity (LOH) and copy number revealed that more than half (56.3%) of the 254 identified LOH loci showed no copy-number(More)
BACKGROUND Detection of loss of heterozygosity (LOH) in clinical tissue samples is frequently difficult because samples are usually contaminated with noncancerous cells or because tumor cells in single tissues have genetic heterogeneity, and the precision of available techniques is insufficient for reliable analysis in such materials. We hypothesized that(More)
