Objective(s): The population in Iran is a genetic admixture of the ancestral Aryan and other populations neighboring Iran. Different ethnic groups in Iran show wide regional distributions for many human leukocyte antigen (HLA) alleles. Therefore, it is necessary and sensible to study the differences in HLA allele distribution in different area. We studied the HLA class I and II allele frequenci...

  Background and Objective: The outcome of hepatitis B virus (HBV) infection may be influenced by host factors like Human Leukocyte Antigen (HLA). We have investigated HLA-A and DRB1 alleles in patients with persistent hepatitis B infection compared to subjects who had spontaneously recovered from HBV infection. To complete the findings of this study we performed another survey in certain HLA ...

Background and Aims: The human leukocyte antigen-E (HLA-E) is a member of non-classical HLA class-I genes which is highly conserved through evolution. In general, so far 25 alleles of HLA-E have been described. However, the existence of only two allelic group; HLA-E*01:01 and HLA-E*01:03 have been demonstrated in all the populations. HLA-E*01:01 and HLA-E*01:03 differ only at codon 107 of exon ...

Background: Human leukocyte antigens (HLA) are polymorphic cell surface proteins. Distribution of HLA alleles vary among different racial and ethnic populations in unrelated stem cell registries. Determination of HLA allele frequencies in different ethnic groups is useful for population genetic analyses. Materials and Methods: Based on data available from the Iranian Stem Cell Donor Registry...

Objective: This study aimed to investigate the association between HLA alleles and visceral leishmaniasis (VL) in a sample of Iraqi patients. Methods: A total of 30 patients were studied, in addition to 20 age, gender and ethnicity matched controls. All subjects were genotyped by polymerase chain reaction-sequence specific primers (PCR-SSP) method. Results: For HLA-class I region (A and B loci)...

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 Researc...

Background: Pulmonary tuberculosis (PT) is one of the endemic diseases in Iraq, and among the suggested predisposing factors are alleles of the human leukocyte antigen (HLA) system. We sought to investigate the association between HLA-class I (A and B) and -class II (DR and DQ) alleles in a sample of PT Iraqi patients.Methods: lymphocytes of 105 PT patients and 40 controls were phenotyped for H...

Introduction Systemic Lupus Erythematosus (SLE) is a complex autoimmune and inflammatory disease. Many studies show HLA alleles can be associated with SLE. The aim of this study was to determine the association of HLA-DRB1 alleles with juvenile- onset in Iranian children. Materials and Methods At a case – control study, 31 children with systemic lupus erythematosus (case group) who referred to ...
