Living with Visceral neuropathy, familial, 1, autosomal recessive

A condition in which nerves of the gut did not develop properly, causing a bowel blockage-like problem without a physical blockage.

Understanding Visceral neuropathy, familial, 1, autosomal recessive

Familial visceral neuropathy 1 is a form of chronic intestinal pseudo-obstruction in which gut nerves did not develop or move into place properly.

The result is a bowel that acts as if it is blocked. GARD says signs can begin at any time in life. Listed features include poor absorption of food, repeated infections, and some heart and diaphragm differences.

Signs & symptoms

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

  • Bowel that acts blocked (pseudo-obstruction)
  • Trouble absorbing food (malabsorption)
  • Repeated infections
  • Heart wall opening (septal defect)
  • Open blood vessel near the heart (patent ductus arteriosus)
  • Hole in the diaphragm (hernia)

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 ERBB3 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
