Pemphigus vulgaris (PV) is an acquired autoimmune blistering disease characterized by the production of autoantibodies targeting desmosomal cadherins, primarily desmoglein 1 and 3, leading to acantholysis. The etiology PV multifactorial, including genetic susceptibility. This retrospective study aimed evaluate association HLA class II alleles examine impact PV-associated on concentration anti-d...

BACKGROUND Data on allele frequencies (AFs) and haplotype frequencies (HFs) of HLA-C and -DQB1 are limited in Koreans. We investigated AFs and HFs of HLA-A, -B, -C, -DRB1, and -DQB1 in Koreans by high-resolution sequence-based typing (SBT). METHODS Hematopoietic stem cells were obtained from 613 healthy, unrelated donors to analyze HLA-A, -B, -C, -DRB1, and -DQB1 genotypes by using AlleleSEQR...

HLA-DQB1 is widely considered to be the major histocompatibility complex (MHC) susceptibility gene for type 1 diabetes (T1D). However, since inheritance of the gene in T1D is recessive, the presence of the protective HLA-DQB1 0602 allele with normal nucleotide sequence in some patients raises the question of whether HLA-DQB1 is not the susceptibility locus itself but merely a good marker. HLA-D...

Intermediate-resolution HLA-DQ typing has gained importance in organ transplantation recently. We evaluated the performance of the LIFECODES HLA-DQB1 typing kit (Immucor, USA) using sequence-specific oligonucleotide (SSO) probe and Luminex platform (Luminex Corp., USA) on 100 samples tested by sequence-based typing (SBT) using the AlleleSEQR HLA-DQB1 kit (Abbott Molecular, USA) in Korean indivi...

Narcolepsy, a sleep disorder characterized by excessive daytime sleepiness, cataplexy and rapid eye movement sleep abnormalities, is tightly associated with human leukocyte antigen HLA-DQB1*06:02. DQB1*06:02 is common in the general population (10-30%); therefore, additional genetic factors are needed for the development of narcolepsy. In the present study, HLA-DQB1 in 664 Japanese narcoleptic ...

In Uyghur women, mortality rates from cervical cancer are amongst the highest in the nation, and genetic susceptibility probably plays a role in the pathogenesis of the disease. We investigated the correlation between polymorphisms of the HLA-DQB1 allele and cervical cancer in Xinjiang Uyghur women. Cervix tissue samples from 80 cases of cervical cancer and 80 cases of cervicitis were genotyped...

conclusions our investigation demonstrated that there is a highly significant association between the studied alleles and t1d. it can be construed that haplotype hla-dr3-dq2 has a very modest effect with respect to the risk of t1d. patients and methods this study was a case-control study. the number of samples was determined using the cochran formula. eighty unrelated t1d patients, including 42...

asthma is a complex and multifactorial disorder. several studies have reported association between different hla- dqb1 and hla- drb1 alleles and allergic asthma. the aim of the present study was to investigate the association of hla-class ii alleles and haplotypes, with total serum ige and the results of the skin prick test in iranian children with allergic asthma. a total of 112 patients with ...

background: a common human leukocyte antigen (hla) class ii allele, dqβ1*03:01, seems to be associated with bullous pemphigoid (bp) in caucasians whereas previous studies in other ethnic groups showed other hla class ii alleles as genetic predisposing factors for bp. objective: to investigate the association of hla class ii alleles and haplotypes with bp in iranian population. methods: fifty pa...

Background: Different studies have demonstrated that a small proportion of healthy individuals receiving the hepatitis B (HB) vaccine do not produce protective levels of anti-HB antibody, a phenomenon which could be linked to certain human leukocyte an-tigen (HLA) class-II alleles or haplotypes. Objectives: The present study was under-taken to determine the frequency of HLA class-II alleles in ...
