MHC Class I related chain A (MICA), Human Leukocyte Antigen (HLA)-DRB1, HLA-DQB1 genotypes in Turkish patients with ulcerative colitis

Abstract

Objectives: We aimed to determine Human LeukocyteAntigen (HLA)-DRB1, DQB1, and MHC Class I related chainA (MICA) genotypes in patients with ulcerative colitis.Methods: HLA-DRB1, HLA-DQB1, MICA genotyping ofpatient (n:85) and controls (n:100) were performed by PCRSSOLuminex (One Lambda genotyping kit).Results: We found significantly higher DRB1*01 (p:0.022,OR:0.23, CI:0.06–0.8) and MICA*0002/20/55 (p:0.03,OR:0.53, CI:0.29–0.93) alleles in control group whereasDRB1*14 (p:0.04, OR:2.25, CI:1–5.08), DRB1*15 (p:<0.0001,OR:4.54, CI:2.09–9.88) and MICA*0004 (p:0.01, OR:2.84,CI:1.2–6.7) alleles were higher in patient group.Conclusions: The present study will inform the MICAand HLA genotypes about the protective (DRB1*01,MICA*0002/20/55) or susceptible (DRB1*14, DRB1*15,MICA*0004) alleles of the disease and helps the literatureon Turkish patients with ulcerative colitis.
