CD1 gene polymorphism and susceptibility to celiac disease: Association of CD1E*02/02 in Moroccans.

CD1 gene polymorphism and susceptibility to celiac disease: Association of CD1E*02/02 in Moroccans. Hum Immunol. 2020 May 25;: Authors: Aureli A, Aboulaghras S, Oumhani K, Del Beato T, Sebastiani P, Colanardi A, El Aouad R, Ben El Barhdadi I, Piancatelli D Abstract CD1 glycoproteins are a class of antigen presenting molecules that bind and present non-peptidic antigens (lipids and glycolipids) for immune recognition. CD1 polymorphisms, although limited, could have a critical role in antimicrobial, anticancer, and autoimmune responses and disease susceptibility. Ethnic differences and interactions between genetic and environmental factors make it attractive the study of these molecules in autoimmune inflammatory disorders, such as celiac disease (CD), in which a strong genetic predisposition (HLA-DQ2/DQ8) and pressure of environmental factors have a central role. CD1A, CD1D and CD1E polymorphisms in exon 2 were assessed in patients from Morocco affected by CD, using direct sequencing analysis, in order to investigate possible associations with the disease in a North African population. Differences in genotype and haplotype distribution of CD1E between celiac patients and controls were found: in particular, an increase of CD1E*02/02 homozygous (OR 2.93, CI 1.30-6.59, p = 0.007) and CD1A*02-E*02 estimated haplotypes in CD, compared with controls. Frequencies of CD1A and CD1D genotypes/alleles were not different between groups. CD1E*02...
