Results: PTPRK was reduced in Gluten Containing Diet–Celiac Disease (GCD–CeD) and Potential-Celiac Disease(Pot-CeD) biopsies (p < 0.01–p < 0.05) whereas pEGFR (p < 0.01 p < 0.01), pERK (p < 0.01 p < 0.01) and proliferation were increased. The gene discussed is PTPRK; the disease is cranioectodermal dysplasia.
