We established a specific genotyping assay for HLA-A*01, which is one of the most frequently found HLA-A alleles in the Caucasian population. This assay uses the polymerase chain reaction (PCR) with allele group-specific primers (ASP). HLA-A*01 group-specific primers were designed for exon 3 of the HLA-A gene, based on the recent HLA-sequence alignment. Both sense and anti-sense primers were de...

UNLABELLED The HLA-DRB1 alleles encoding an amino acid sequence (QKRAA/QRRAA/RRRAA) at position 70 74 of the third hypervariable region of the β1 chain of the HLA-DRB1 gene, called shared epitope (SE), are associated with increased susceptibility to and severity of rheumatoid arthritis (RA) in different populations. OBJECTIVE To determine the frequency of HLA-DRB1 alleles in Brazilian patient...

OBJECTIVES To analyze the distribution of HLA alleles and HLA microsatellite alleles in Croatian patients with testicular carcinoma, compare it with that of healthy controls and investigate whether the polymorphism within the HLA region could be associated with the development of testicular cancer. METHODS Genomic DNA was isolated from the peripheral blood of 24 patients with testicular germ ...

Genetic variations of human leukocyte antigen (HLA) genes within the major histocompatibility complex (MHC) locus are strongly associated with disease susceptibility and prognosis for many diseases, including many autoimmune diseases. In this study, we developed a Korean HLA reference panel for imputing classical alleles and amino acid residues of several HLA genes. An HLA reference panel has p...

BACKGROUND Various studies worldwide suggest that human leukocyte antigen (HLA) region may be involved in the genetic susceptibility of vitiligo but little information is available from India. AIM To find the HLA associated susceptibility to develop vitiligo in Indian patients and to detect role of HLA in familial vitiligo. METHODS This was a case controlled study which included all patient...

INTRODUCTION The present study was designed to investigate a possible role of HLA (histocompatibility leucocyte antigen) class-I alleles (HLA-A, -B, and -C) in leprosy patients from Southern Brazil. METHODS Two hundred and twenty-five patients with leprosy and 450 individuals for the control group were involved in this research. HLA genotyping was performed through PCR-SSO protocols (One Lamb...

Human leukocyte antigen (HLA) class I alleles can be grouped into supertypes according to their shared peptide binding properties. We examined alleles of the HLA-B58 supertype (B58s) in treatment-naïve human immunodeficiency virus type 1 (HIV-1)-seropositive Africans (423 Zambians and 202 Rwandans). HLA-B and HLA-C alleles were resolved to four digits by a combination of molecular methods, and ...

Celiac disease (CD) is a chronic inflammatory disease in the small intestine triggered by gluten uptake that occurs in genetically susceptible individuals. HLA-DQ2 protein encoded by HLA-DQA1*05 and DQB1*02 alleles is found in 90-95% of CD patients. All of the remaining patients carry HLA-DQ8 protein encoded by HLA-DQA1*03 and DQB1*03:02 alleles. Specific HLA-DQ genotypes define different risk ...

background: rheumatoid arthritis (ra) is the most common chronic inflammatory erosive joint disease with the worldwide distribution of approximately 0.5-1%. molecular methods can be very sensitive in the early stage diagnosis of the disease and therefore prevention the late complications and disabilities. etiology of ra, an autoimmune disease, is not exactly known but immunologic and genetic fa...

Our objective was to determine whether the presence of the human leukocyte antigen HLA-DRB1 locus is associated with production of anti-cyclic citrullinated peptide antibodies (anti-CCP Abs) and to what extent they are associated with increased susceptibility to and severity of rheumatoid arthritis (RA) in Egyptian patients. Twenty-nine RA patients gave informed consent to participate in a case...
