Living with Congenital diarrhea 5 with tufting enteropathy

A rare inherited condition with severe diarrhea starting in newborns because of changes in the lining of the intestine.

Understanding Congenital diarrhea 5 with tufting enteropathy

Congenital tufting enteropathy (congenital diarrhea 5) is a rare inherited intestinal condition with early, severe diarrhea.

Diarrhea begins very early, is severe and hard to treat, and can lead to intestinal failure. Babies can become dehydrated and gain weight slowly. It starts in newborns and infants.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Chronic watery diarrhea
  • Dehydration
  • Slow weight gain (failure to thrive)
  • Poor absorption of food
  • Swollen belly
  • Irritability

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include digestive system specialists and genetic specialists.

  3. Consider genetic testing

    Changes in EPCAM are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
