  Objectives: Rheumatoid Arthritis (RA) is a multifactorial autoimmune disease affecting synovial joints, surrounding tissues, and many other organs of the human body. HLA-DRB1 has a major role in the immune system by presenting peptides derived from extracellular proteins on antigen presenting cells and has been associated with RA. In this study, we screened for HLA-DRB1 mutations in Omani patients affected with RA. Methods: Thirty blood samples from affected patients were examined in parallel with fourteen healthy control samples. HLA-DRB1 mutational status was examined using polymerase chain reaction (PCR) and sequencing. Results: A total of 75 aberrations were identified in HLA-DRB1, of which 20% were polymorphisms. From the reported aberrations, 25.5% were silent mutations. Within exon-2, three non-synonymous mu.. View More»
