Living with Vici syndrome

A condition that starts early in life and affects the brain, immune system, heart, skin, and eyes.

Understanding Vici syndrome

Vici syndrome is a disorder that begins early in life and affects many body systems.

Brain differences include a missing connection between the two halves of the brain (agenesis of the corpus callosum) and a small head. Children have low muscle tone and profound developmental delays. Weak immune function leads to repeated infections, and heart muscle disease is common.

Signs & symptoms

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

  • Missing brain connection (corpus callosum)
  • Global developmental delay
  • Low muscle tone (hypotonia)
  • Repeated infections
  • Heart muscle disease (cardiomyopathy)
  • Seizures

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 allergy and immune system specialists, brain and nervous system specialists, eye disease specialists and genetic specialists.

  3. Consider genetic testing

    Changes in EPG5 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    Children's Cardiomyopathy Foundation and Immune Deficiency Foundation may keep lists of experts for this condition.

Quick facts

Symptoms usually startduring Pregnancy and as a Newborn
InheritanceAutosomal Recessive
GenesEPG5

Vici syndrome is caused by changes in the EPG5 gene. A child inherits a changed copy of the gene from each parent (autosomal recessive).
