Distribution of HLA-B*27 Alleles in Pa-tients with Ankylosing Spondylitis in Iran
Background: HLA-B*27 is strongly associated with ankylosing spondylitis (AS). It represents a family of alleles that differ among ethnic groups. Objective: The aim of this study was to determine the distribution of HLA-B*27 alleles in AS patients and healthy controls in Isfahan (Iran). Methods: Sixty AS patients and 430 healthy blood donors were selected. All subjects were HLA-B*27 positive by ...
متن کاملInhibitory Killer Cell Immunoglobulin-Like Receptor KIR3DL1 in Combination with HLA-B Bw4iso Protect against Ankylosing Spondylitis
Background: The HLA class I molecules serve as ligands for both T cell receptors and killer cell immunoglobulin-like receptors (KIRs). Objective: We investigated the HLAC and HLA-Bw4 alleles as well as KIRs expression on CD56 positive lymphocytes to evaluate whether these genes and molecules could influence Ankylosing spondylitis (AS) susceptibility, alone or in combination. Methods: We typed 4...
متن کاملASSOCIATION OF HLA-B27 WITH ANKYLOSING SPONDYLITIS IN ISFAHAN, IRAN
Using a standard microcytotoxicity (NIH) technique of tissue typing, the HLA-B27 antigen was identified in 30 out of 34 patients (HH.2%) with classical ankylosing spondylitis (AS), compared to 6 out of 70 controls (H.6%) (P < 0.005). We also found this antigen in 8 out of 76 (10.5%) patients with non-AS arthritis.
متن کاملPolymorphism of HLA-B27: 105 subtypes currently known.
HLA-B27 has a high degree of genetic polymorphism, with 105 known subtypes, named HLA-B*27:01 to HLA-B*27:106, encoded by 132 alleles. The most common subtypes associated with ankylosing spondylitis are HLA-B*27:05 (Caucasians), HLA-B*27:04 (Chinese), and HLA-B*27:02 (Mediterranean populations). For Chinese populations, HLA-B*27:04 is associated with a greater ankylosing spondylitis risk than H...
متن کاملLack of association of the G22A polymorphism of the ADA gene in patients with ankylosing spondylitis.
Genes located outside the HLA region (6p21) have been considered as candidates for susceptibility to ankylosing spondylitis. We tested the hypothesis that the G22A polymorphism of the adenosine deaminase gene (ADA; 20q13.11) is associated with ankylosing spondylitis in 166 Brazilian subjects genotyped for the HLA*27 gene (47 patients and 119 controls matched for gender, age and geographic ...
