Definition:

Tricho-hepato-enteric syndrome (THE), also known as syndromic diarrhea (SD), is a congenital enteropathy presenting with early-onset severe intractable diarrhea and associated with non-specific villous atrophy with low or no mononuclear cell infiltration of the lamina propria nor specific histological abnormalities involving the epithelium. Infants are born small for gestational age. Patients present with facial dysmorphism, immune disorders and, in some patients, early onset of severe liver cirrhosis. It has been linked to abnormalities in two components of the putative human ski complex: SKIV2L and TTC37. During their clinical course, most of the patients require parenteral nutrition and often immunoglobulin supplementation.
