We retrospectively analyzed results for 154 patients with acquired severe aplastic anemia who received bone marrow transplants between 1993 and 2000 from unrelated donors identified through the Japan Marrow Donor Program. Patients were aged between 1 and 46 years (median, 17 years). Seventy-nine donor-patient pairs matched at HLA-A, -B, and -DRB1 loci, as shown by DNA typing. Among the 75 misma...

Human leukocyte antigen (HLA) gene region encodes a set of HLA molecules functioning critical roles in immune response. Each HLA gene locus shows extensive polymorphism with ever-increasing number of alleles. The HLA nomenclature system for alleles defined by DNA typing was first established in 1987 and has been revised several times. Recently, it has been revised again with a new frame that ca...

Introduction: Recognition of human leukocyte antigens (HLA) is of importance for hematopoietic stem cell transplantation. Any HLA-mismatches between the donor and recipient can cause graft rejection or other complications. In HLA-typing experiments, usage of HLA-known reference cells accompany with HLA-unknown samples is obligatory. Some international centers represent these cells with high e...

background: hla compatibility between transplant donor and recipient is one of the major determinants of transplant outcome. objective: to determine hla class i by pcr- sequence-specific oligonucleotide probe (pcr-ssop) in cord blood donors. methods: genomic dna of 142 cord blood samples registered at the cord blood bank of iran at hematology, oncology, and bone marrow transplantation research ...

conclusions aih in our region presents with advanced disease affecting predominantly children and adolescents. there is a genetic association of hla dr6 along with other alleles and antigens in our patients with aih. objectives the aim of this study was to evaluate the clinical profile of autoimmune hepatitis (aih), and determine the associated antigens and alleles by performing hla typing. pat...

33 34 The human leukocyte antigen (HLA) genes code for proteins that play a central role in the 35 function of the immune system by presenting peptide antigens to T cells. As HLA genes show 36 extremely high genetic polymorphism, HLA typing on the allele level is demanding and is based 37 on DNA sequencing. Determination of HLA alleles is warranted as many HLA alleles are major 38 genetic facto...

The past decade has seen human leukocyte antigen (HLA) typing emerge as a remarkably popular test for the diagnostic work-up of coeliac disease with high patient acceptance. Although limited in its positive predictive value for coeliac disease, the strong disease association with specific HLA genes imparts exceptional negative predictive value to HLA typing, enabling a negative result to exclud...

Human leukocyte antigen (HLA) typing from next generation sequencing (NGS) data has the potential for applications in clinical laboratories and population genetic studies. Here we introduce a novel technique for HLA typing from NGS data based on read-mapping using a comprehensive reference panel containing all known HLA alleles and de novo assembly of the gene-specific short reads. An accurate ...
