of Tufting Enteropathy Caused by Mutation p.Asp253Asn and Absent EPCAM Expression.

Tufting enteropathy (TE) is caused by recessive epithelial cell adhesion molecule () mutations, features congenital intractable diarrhea, growth retardation, and a characteristic disorganization of surface enterocytes. TE generally requires parenteral nutrition (PN) throughout childhood and into adulthood or a small bowel transplantation. We report 2 siblings with TE; a 3-year-old patient 1 intermittently receives partial PN, monthly somatostatin therapy, tolerates a normal diet and has a normal stool output.

The FMS like Tyrosine Kinase 3 (FLT3) Is Overexpressed in a Subgroup of Multiple Myeloma Patients with Inferior Prognosis.

Therapy resistance remains a major challenge in the management of multiple myeloma (MM). We evaluated the expression of FLT3 tyrosine kinase receptor (FLT3, CD135) in myeloma cells as a possible clonal driver. FLT3 expression was analyzed in bone marrow biopsies of patients with monoclonal gammopathy of undetermined significance or smoldering myeloma (MGUS, SMM), newly diagnosed MM (NDMM), and relapsed/refractory MM (RRMM) by immunohistochemistry (IHC).
