We conducted an association study across the human leukocyte antigen (HLA) complex to identify loci associated with multiple sclerosis (MS). Comparing 1927 SNPs in 1618 MS cases and 3413 controls of European ancestry, we identified seven SNPs that were independently associated with MS conditional on the others (each P ≤ 4 x 10(-6)). All associations were significant in an independent replicatio...
The susceptibility to multiple sclerosis (MS), a chronic neurological autoimmune disease that primarily targets CNS myelin, has long been associated with HLA class-II genes. Although several other HLA and non-HLA disease predisposing alleles have been identified, alleles of the HLA-DR15 haplotype (DRB1*1501, DRB5*0101, and DQB1*0602) remain the strongest susceptibility factor. Many studies have...
Multiple sclerosis (MS) is a chronic inflammatory disease with a substantial genetic component. Since the discovery of anti-aquaporin-4 (AQP4) antibodies, a specific biomarker for neuromyelitis optica (NMO), NMO has been classified as a distinct disease entity with a fundamentally different etiology from MS. Recent genetic studies have clarified the distinct and common genetic profiles of Japan...
BACKGROUND Previous studies indicate that the frequency distributions of HLA alleles and haplotypes vary from one ethnic group to another or between the members of the same ethnic group living in different geographic areas. It is necessary and meaningful to study the high-resolution allelic and haplotypic distributions of HLA loci in different groups. METHODOLOGY/PRINCIPAL FINDINGS High-resol...
Previous studies demonstrated significant differences in a number of HLA allele frequencies in leukemia patients and normal subjects. In this study, we have analyzed HLA class II alleles and haplotypes in 110 leukemia patients (60 acute myelogenous leukemia "AML", 50 chronic myelogenous leukemia"CML") and 180 unrelated normal subjects. Blood samples were collected from all of the patients and c...
Genetic control of immune reactions has a major role in the development of rheumatic heart disease (RHD) and differs between patients with rheumatic fever (RF). Some authors think the risk of acquiring RHD is associated with the HLA class II DR and DQ loci, but other views exist, due to the various HLA-typing methods and ways of grouping cases. Our goal was to determine the relations between HL...
BACKGROUND & OBJECTIVES Human papillomavirus (HPV) is the main causative agent for cervical cancer. Variability in host immunogenetic factors is important in determining the overall cellular immune response to the HPV infection. This study was carried out to confirm the association between human leukocyte antigen (HLA) class II alleles and cervical cancer in HPV infected women. METHODS Both l...
The clinical importance of HLA class II gene disparity in unrelated stem cell transplantation is not entirely known. The impact was evaluated of matching donors and recipients for HLA-DR, HLA-DQ, and HLA-DP genes on clinical outcome after stem cell transplantation for chronic myeloid leukemia (CML) performed between 1988 and 1997. HLA-DRB1, -DQA1, -DQB1, -DPA1, and -DPB1 alleles were identified...
BACKGROUND Polymyositis (PM) and dermatomyositis (DM) are idiopathic inflammatory myopathies. Genetic variability in human leukocyte antigen (HLA) genes plays an important role in the pathogenesis of PM and DM. However, few studies on the subject in Chinese populations have been reported thus far. METHODS We studied the influence of HLA polymorphisms on DM and PM susceptibility by analyzing H...
The presence of oligoclonal bands (OCB) in cerebrospinal fluid (CSF) is a typical finding in multiple sclerosis (MS). We applied data from Norwegian, Swedish and Danish (i.e. Scandinavian) MS patients from a genome-wide association study (GWAS) to search for genetic differences in MS relating to OCB status. GWAS data was compared in 1367 OCB positive and 161 OCB negative Scandinavian MS patient...
