Celiаc diseаse is аn immune disоrder that is triggered by an envirоnmental agent (gluten) in genetically predispоsed individuals. The genetic basis of the disease is shown by the frequent intra-familial occurrence. Select all correct answer/s. 1. There is close association with the human leukocyte antigen (HLA) DR-DQ2 and/or DR4-DQ8 gene locus 2. More than 99% of individuals with celiac disease have HLA DR3-DQ2 and/or DR4-DQ8 3. Homozygotes for DR3-DQ2 are at the highest risk for celiac disease 4. While the presence of either the HLA-DQ2 or DQ8 genotype is essential to confer disease, it is not sufficient, and environmental factors and other genes at non-HLA loci must also participate
