PURPOSE We investigated whether particular HLA-DRB1 polymorphisms contribute to egg allergy development in Korean children with atopic dermatitis (AD). METHODS HLA-DRB1 alleles were determined by PCR-sequence-specific oligonucleotide (SSO) and PCR-single-strand conformation polymorphism (SSCP) methods in 185 patients with AD and 109 normal control (NC) subjects. AD patients were divided into ...

AIM To determine genetic polymorphisms at human leukocyte antigen (HLA)-A, -B, and -DRB1 loci in Han population of Xi'an city in China. METHODS Polymerase chain reaction-based reverse line-strip sequence specific oligonucleotide hybridization was used to determine the alleles of HLA-A, -B, and -DRB1 in 516 unrelated, healthy individuals of Han population in Xi'an. Allele frequencies at HLA-A,...

Cytoplasmic protein aggregates are one of the pathological hallmarks of neurodegenerative disorders, including amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD). Several RNA-binding proteins have been identified as components of inclusion bodies. Developmentally regulated RNA-binding protein 1 (Drb1)/RNA-binding motif protein 45 is an RNA-binding protein that was ...

Whereas the genetic risk for type 1 diabetes is linked to human leukocyte antigen (HLA) class II genes, the HLA association in type 2 (non-insulin-dependent) diabetes is less clear. The association between HLA class II genotypes and type 2 diabetes was examined in adult Bahrainis, an Arab population with a high prevalence of type 2 diabetes. HLA-DRB1* and -DQB1* genotyping of 86 unrelated type ...

The major histocompatibility complex (MHC) is one of the biological systems of major polymorphisms. The study of HLA class II variability has allowed the identification of several alleles that are characteristic to Amerindian populations, and it is an excellent tool to define the relations and biological affinities among them. In this work, we analyzed the allelic distribution of the HLA-DRB1 c...

The polymorphism of human leukocyte antigen (HLA), which is a genetic factor that influences the progression of hemorrhagic fever with renal syndrome (HFRS) after Hantaan virus (HTNV) infection, was incompletely understood. In this case-control study, 76 HFRS patients and 370 healthy controls of the Chinese Han population were typed for the HLA-A, -B, and -DRB1 loci. The general variation at th...

INTRODUCTION Giant cell arteritis (GCA) is an autoimmune disease commonest in Northern Europe and Scandinavia. Previous studies report various associations with HLA-DRB1*04 and HLA-DRB1*01; HLA-DRB1 alleles show a gradient in population prevalence within Europe. Our aims were (1) to determine which amino acid residues within HLA-DRB1 best explained HLA-DRB1 allele susceptibility and protective ...

BACKGROUND In this study, we used high-resolution DNA typing to investigate the distribution of HLA alleles and haplotypes in Koreans. METHODS HLA-A, -B, -C, and -DRB1 alleles were genotyped at the allelic (4-digit) level in 474 healthy Koreans. HLA genotyping was performed in two steps. Initially, serologic typing or generic-level DNA typing was performed using the PCR-sequence-specific olig...

We established a genetic database by investigating human leukocyte antigen (HLA)-DRB1 allelic frequencies in a disease-association study in the Tujia population in Wufang, Hubei, China. The allele frequencies of the HLA-DRB1 locus in 262 healthy, unrelated Tujia individuals living in the Wufeng region of the Hubei Province were analyzed using the Luminex HLA sequence-specific oligonucleotide me...
