Lack of EPCAM protein expression caused by the p.Asp253Asn mutation. There was no EPCAM staining detected in FFPE slides of duodenal biopsies from patients 1 (A; H&E, magnification 4× and 20×; EPCAM immunohistochemistry, magnification 4×, 10×, 20×, and 40×) and patient 2 (B; H&E, magnification 4× and 20×; EPCAM immunohistochemistry, magnification 4×, 10×, 20×, and 40×), as compared to an on-slight control (C; EPCAM immunohistochemistry, magnification 4×, 20×, and 40×) using a monoclonal EPCAM antibody (Clone Ber-EP4, Cell Marque, Millipore Sigma). EPCAM, epithelial cell adhesion molecule.
