Overview
It is a rare genetic disorder presenting in children less than 1 year of age.[1]
Pathophysiology
- It is a genetic disorder with an autosomal recessive inheritance pattern.
- Mutations in TTC37 which encodes the putative protein Thespin, have recently been associated with Tricho-Hepato-Enteric syndrome. [2]
Natural History, Complications and Prognosis
- Prognosis is poor.
- Many patients die before the age of 5 due to infections or cirrhosis.
Diagnosis
Symptoms
- Intractable diarrhea
- Intrauterine growth retardation
- Hair abnormalities - prominent forehead and cheeks, a broad nasal root and widely spaces eyes (hypertelorism)
- Facial abnormalities - their hairs are woolly, easily removed and poorly pigmented
Laboratory Tests
Biopsy
- Small bowel - villous atrophy with low or no mononuclear cell infiltration of the lamina propria
- Microscopic analysis of the hair - twisted hairs of unequal size and different shapes
Other Diagnostic studies
- Scanning electron microscopy of hair - hair budding
- Biochemical analysis of hair reveal - sulfur-deficient brittle hair
- Abnormal antibody generation - T cell dysfuntion
Treatment
- No specific treatment
- Total parenteral nutrition may reduce symptoms of diarrhea
- Avoiding further damage to the liver
