Learn About Trichohepatoenteric Syndrome

What is the definition of Trichohepatoenteric Syndrome?

Trichohepatoenteric syndrome is a condition that affects the hair (tricho-), liver (hepato-), and intestines (enteric), as well as other tissues and organs in the body. This condition is also known as syndromic diarrhea because chronic, difficult-to-treat diarrhea is one of its major features. Within the first few weeks of life, affected infants develop watery diarrhea that occurs multiple times per day. Even with nutritional support through intravenous feedings (parenteral nutrition), many of these children experience failure to thrive, which means they do not gain weight or grow at the expected rate. Most children with trichohepatoenteric syndrome are small at birth, and they remain shorter than their peers throughout life.

What are the causes of Trichohepatoenteric Syndrome?

Trichohepatoenteric syndrome can be caused by mutations in the TTC37 or SKIV2L gene. These genes provide instructions for making proteins whose functions have not been confirmed. Researchers speculate that they work together with other proteins within cells to help recognize and break down excess or abnormal messenger RNA (mRNA) molecules. mRNA is a chemical cousin of DNA that serves as the genetic blueprint for protein production. Studies suggest that getting rid of excess and abnormal mRNA is important for cell growth.

How prevalent is Trichohepatoenteric Syndrome?

Trichohepatoenteric syndrome is a rare condition with an estimated prevalence of about 1 in 1 million people. At least 44 cases have been reported in the medical literature.

Is Trichohepatoenteric Syndrome an inherited disorder?

This condition is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.
