CeD is an autoimmune‐like disease caused by a harmful immune response to dietary gluten proteins of wheat (α‐, γ‐, ω‐gliadins, and glutenins), barley (hordeins), and rye (secalins). Patients with CeD have CD4+ T cells that recognize deamidated gluten peptides bound to the CeD‐associated human leukocyte antigens (HLA) molecules HLA‐DQ2.5, HLA‐DQ2.2, or HLA‐DQ8 [1]. Here, CD4 is linked to cranioectodermal dysplasia.
