Interestingly, antigens such as GroEL, gGT, UreA, and possibly both vacA and cagA from H. pylori or other bacteria with similar antigens [33, 34] may affect the expression of CeD, potentially delaying the clinical diagnosis of CeD if infected with H. pylori early in life. The gene discussed is S100A8; the disease is cranioectodermal dysplasia.
