Vici Syndrome

Vici syndrome is a very rare genetic condition that starts early in life and affects many organs at the same time. The condition is usually caused when a child inherits two non-working copies of a gene called EPG5—one from each parent. This gene helps cells perform autophagy, a basic “self-cleaning/recycling” process. When EPG5 does not work properly, waste builds up inside cells, and this can damage the brain, eyes, heart, immune system, muscles, and skin/hair pigment. Classic “core” findings include: agenesis of the corpus callosum (the big cable connecting the two brain halves does not form), cataracts, hypopigmentation (lighter coloring of skin/hair/eyes), cardiomyopathy (weak heart muscle), and combined immunodeficiency (weakened defenses against infections). Children often have severe developmental delay, feeding difficulties, poor growth, and are prone to recurrent infections. Because many systems are involved, care usually requires a coordinated team.

Vici syndrome is a very rare, serious genetic condition that starts early in life and affects many body systems at the same time. It is caused by harmful changes (mutations) in a gene called EPG5. This gene normally helps the cell’s “recycling system” (called autophagy) work properly. When EPG5 is not working, cells cannot clear out damaged parts and waste, so many organs—especially the brain, immune system, heart, eyes, and skin—do not develop or function normally. Children commonly have missing or underdeveloped connections between the two halves of the brain (agenesis of the corpus callosum), cataracts, light skin/hair/eye color (hypopigmentation), heart muscle weakness (cardiomyopathy), and immune problems that lead to frequent infections. Most babies also show low muscle tone (hypotonia), feeding and swallowing difficulties, poor weight gain, seizures, and developmental delay. There is no single cure right now; treatment focuses on supportive, multidisciplinary care to prevent complications and improve quality of life. GARD Information CenterOrpha.netBioMed CentralNCBI

In medical terms, Vici syndrome is part of an EPG5-related disorder spectrum. It is usually autosomal recessive (both gene copies altered). The underlying biology is a defect in autophagosome–lysosome fusion, so the “recycling bag” in the cell cannot merge with the “digesting bin,” causing toxic buildup. This explains why so many organs are affected at once. NCBINatureScienceDirect

Types

There is no single official “type list” used in clinics, but experts increasingly talk about a spectrum of EPG5-related disease. It helps families to think about types in terms of how severe and which organs are most affected:

1. Classic / severe multisystem form
   Starts in the newborn period or early infancy. The core pentad (absent corpus callosum, cataracts, hypopigmentation, cardiomyopathy, immunodeficiency) is common. Most children have profound developmental delay, feeding problems, recurrent infections, and multi-organ involvement. BioMed Central

2. Attenuated / milder phenotypes (variant forms)
   Some children with particular EPG5 variants show less severe disease and may live longer; specific founder variants have been reported with milder clinical courses compared with the classic picture. Organ problems may still occur, but timing and intensity can be different. ScienceDirect

3. Organ-dominant presentations (still EPG5-related, but one system draws attention first)
   Examples include cases first noticed due to heart muscle disease, immune problems, or eye findings before the wider picture becomes clear. This is still part of the same spectrum and reflects how autophagy failure can look different at first in different children. Oxford AcademicBioMed Central

Causes

“Cause” here means what leads to the disease or makes it worse. For Vici syndrome, the root cause is genetic—EPG5 variants—but there are many biologic mechanisms and modifiers that explain the full picture:

1. Biallelic EPG5 mutations (autosomal recessive) – child inherits one altered copy from each parent. This is the fundamental cause. PMC

2. Loss-of-function variants – changes that truncate or remove protein function (nonsense, frameshift, large deletions). These typically produce the classic severe phenotype. PMC

3. Missense variants – a single amino-acid change; some are milder or tissue-specific in effect. ScienceDirect

4. Splice-site variants – disrupt the way RNA is processed, leading to faulty protein. PMC

5. Defective autophagosome-lysosome fusion – the “recycling bag” cannot fuse with the “digesting bin,” so waste builds up. Nature

6. Impaired EPG5–Rab7 interaction – EPG5 acts as a Rab7 effector; when this interaction fails, autophagosome maturation stalls. ScienceDirect

7. Accumulation of autophagy cargo – proteins like p62/SQSTM1 and LC3 build up and damage cells (“traffic jam” inside cells). Nature

8. Neuronal development disruption – abnormal brain wiring can cause agenesis of the corpus callosum and later microcephaly. BioMed Central

9. Myofiber autophagic vacuolar myopathy – muscle fibers collect autophagic vacuoles → hypotonia and weakness. BioMed Central

10. Cardiomyocyte autophagy failure – leads to cardiomyopathy (weak or thickened heart muscle). PMC

11. Thymic/immune pathway defects – combined immunodeficiency increases infection risk. Orpha.net

12. Pulmonary immune dysregulation – animal models show altered lung inflammation, explaining recurrent chest infections. Cell

13. Melanosome trafficking problems – causes hypopigmentation of skin, hair, and eyes. Orpha.net

14. Peripheral nerve involvement – some children have reduced reflexes suggesting neuropathy, adding to weakness. BioMed Central

15. Genetic background (modifier genes) – other autophagy-pathway genes may modify severity. PMC

16. Founder effects – shared variants in specific populations can shape a community’s typical disease pattern. ScienceDirect

17. Consanguinity – parents being related increases the chance a child inherits the same rare variant from both sides. (General genetics principle noted in case series.) PMC

18. Nutritional stress/failure to thrive – not a root cause, but worsens outcomes by stressing already fragile systems. MedlinePlus

19. Intercurrent infections – common viral/bacterial illnesses can trigger rapid clinical decline when immune defenses are weak. GARD Information Center

20. Epileptogenesis with proteotoxic stress – emerging research links autophagy failure to seizure risk through toxic protein buildup in neurons. Taylor & Francis Online

1. Global developmental delay – major delays in movement, language, and self-care; often severe. BioMed Central

2. Poor muscle tone (hypotonia) – “floppiness,” weak head control, delayed sitting or walking. BioMed Central

3. Feeding difficulties – trouble sucking and swallowing; frequent choking; leads to failure to thrive. GARD Information Center

4. Growth problems – poor weight gain and acquired microcephaly (head growth slows after birth). PubMed

5. Recurrent infections – ear, chest, gut, and urinary infections due to combined immunodeficiency. GARD Information Center

6. Breathing symptoms – cough, fast breathing, pneumonia episodes (immune and muscle weakness contribute). Cell

7. Seizures – can occur in infancy or childhood; EEG abnormalities are common. PubMed

9. Hearing loss – sensorineural hearing difficulties in some children. GARD Information Center

10. Skin, hair, and eye hypopigmentation – lighter coloring than expected for family background. Orpha.net

11. Heart symptoms – fatigue, poor feeding, sweating with feeds, fast breathing from cardiomyopathy. PMC

12. Neurologic signs – weak or absent reflexes in some, indicating neuropathy. BioMed Central

13. GI issues – reflux, constipation, or diarrhea, often during/after infections. GARD Information Center

14. Facial or structural differences – occasionally cleft palate, small jaw, syndactyly (joined fingers/toes). Wikipedia

15. Learning difficulties/intellectual disability – typically profound because brain wiring is affected from early on. PubMed

Diagnostic tests

Vici syndrome is diagnosed by clinical pattern plus genetic confirmation. Testing looks for hallmark features, checks organ function, and confirms the EPG5 change.

A) Physical exam

1. General pediatric exam with growth charting
   Doctors measure weight, length, and head circumference. Falling percentiles and acquired microcephaly support the diagnosis and guide nutrition plans. PubMed

2. Skin/hair/eye pigmentation check
   Lighter skin, hair, and iris (“hypopigmentation”) compared with family background points toward the Vici pattern. Orpha.net

3. Cardiovascular exam
   Listening for murmurs, gallops, or signs of heart failure (fast breathing, enlarged liver, poor pulses) helps flag cardiomyopathy early. PMC

4. Neurologic exam
   Checks muscle tone, strength, and reflexes. Findings may include hypotonia and sometimes reduced/absent reflexes, suggesting neuropathy or myopathy. BioMed Central

B) Manual / bedside tests

5. Slit-lamp or red-reflex cataract screen
   A quick light-in-the-pupil check (red reflex) or slit-lamp exam can reveal congenital cataracts, a key feature. EyeWiki

6. Cover–uncover and ocular motility exam
   Simple bedside eye movement tests detect nystagmus or strabismus, helping document visual system involvement. EyeWiki

7. Bedside feeding & swallow assessment
   Watching a feed helps identify aspiration risk, poor suck, or coordination problems that contribute to failure to thrive. GARD Information Center

8. Developmental screening
   Age-appropriate checklists (e.g., milestones) quickly capture global delay and guide referrals for therapy and formal testing. BioMed Central

C) Lab & pathological tests

9. Molecular genetic testing of EPG5 (sequencing ± deletion/duplication analysis)
   This is the confirmatory test. Finding two disease-causing EPG5 variants establishes the diagnosis. Family testing can identify carriers. NCBI

10. Immune work-up (immunoglobulin levels and lymphocyte subsets by flow cytometry)
    Looks for combined immunodeficiency that explains frequent infections and guides immunology care. Orpha.net

11. Muscle enzymes (CK), liver enzymes, and basic metabolic panel
    Elevated or sometimes normal CK can accompany myopathy; organ panels track systemic stress and medication safety. BioMed Central

12. Muscle biopsy (if diagnosis unclear)
    Can show autophagic vacuoles and accumulation of p62/LC3, supporting an autophagy defect—used when genetics is inconclusive or unavailable. Nature

13. Infection evaluation during illness (cultures, viral PCRs, inflammatory markers)
    Because recurrent infections are common, targeted testing during episodes helps tailor antibiotics/antivirals. GARD Information Center

D) Electrodiagnostic tests

14. Electroencephalogram (EEG)
    Checks for seizure activity and background abnormalities; helps adjust anti-seizure treatment. PubMed

15. Nerve conduction studies / electromyography (NCS/EMG)
    Clarify whether weakness is from muscle (myopathy) or nerve (neuropathy), which can influence therapy goals. BioMed Central

16. Electrocardiogram (ECG ± Holter)
    Screens for arrhythmias that may accompany cardiomyopathy and guides cardiology follow-up. PMC

E) Imaging tests

17. Brain MRI
    Often shows agenesis of the corpus callosum and can reveal hypomyelination or other structural differences—key in recognizing the syndrome. BioMed Central

18. Echocardiography (heart ultrasound)
    Detects cardiomyopathy (dilated or hypertrophic), valve issues, or congenital heart defects; essential for baseline and follow-up. PMC

19. Chest imaging (X-ray or high-resolution CT when indicated)
    Evaluates recurrent pneumonias, airway changes, and complications of immune dysfunction. Cell

20. Abdominal/renal ultrasound (as indicated)
    Looks for organ enlargement (e.g., liver, spleen) or kidney anomalies sometimes reported in the spectrum; helpful for comprehensive baseline. BioMed Central

Non-Pharmacological Treatments (therapies and others)

(Each item includes what it is, purpose, and simple mechanism.)

1. Coordinated multidisciplinary care

Dietary “Molecular” Supplements

(Supportive only—not disease-modifying; doses are common pediatric/adult ranges and must be tailored by clinicians.)

1. Vitamin D (e.g., 400–1000 IU/day children; 800–2000 IU/day adults): Supports bone/immune health; helps calcium absorption.

2. Omega-3 fatty acids (EPA+DHA) (~50–100 mg/kg/day children; 1–2 g/day adults): May reduce inflammation and support heart function.

3. Coenzyme Q10 (2–5 mg/kg/day children; 100–200 mg/day adults): Mitochondrial cofactor that may support cardiac energy metabolism.

4. L-carnitine (50–100 mg/kg/day children; 1–2 g/day adults): Transports fatty acids into mitochondria; sometimes used with myopathy/feeding issues.

5. Multivitamin with iron (if iron-deficient): Corrects anemia that worsens fatigue and cardiac strain.

6. Zinc (age-appropriate dosing): Important for immunity and wound healing.

7. Selenium (microdose per age): Antioxidant enzyme cofactor; avoid excess.

8. Probiotics (strain/dose per GI): May help antibiotic-associated diarrhea and gut barrier function.

Advanced immune-support / regenerative” therapies

There are no approved “stem-cell drugs” that cure Vici syndrome. A few advanced or adjunct options may be considered case-by-case by specialty teams:

1. Intravenous Immunoglobulin (IVIG) – immune replacement as above; cornerstone when antibody production is poor. PMC

2. Granulocyte colony-stimulating factor (G-CSF) – growth factor used if severe neutropenia occurs to raise neutrophils; dosing and need are individualized by hematology.

3. Rituximab (select scenarios) – B-cell depleting monoclonal antibody considered in complicated immune dysregulation; specialist decision only.

4. Emapalumab (IFN-γ blocker) for HLH-like hyper-inflammation – has been used in severe immune activation episodes reported in EPG5-related disease; strictly tertiary-center use. SpringerLink

5. Sirolimus (rapamycin) in clinical-research settings – theoretical autophagy modulation; not established therapy; consider only on a trial/protocol. PMC

6. Allogeneic hematopoietic stem cell transplantation (HSCT) – not a drug but the closest “regenerative” option to correct severe immune defects; outcomes vary and risks are substantial; considered only after expert immunology/transplant evaluation. Recent IEI series report overall survival around 70–80% across conditions, but Vici-specific decisions weigh systemic involvement and goals of care. Frontiers+1

Surgeries

1. Cataract extraction (with/without IOL)
   Why: Remove cloudy lenses to improve light entry and visual comfort; benefits depend on overall neuro-visual function and medical stability. EyeWiki

2. Gastrostomy tube (G-tube) placement
   Why: Secure nutrition/hydration when swallowing is unsafe or intake is inadequate; reduces aspiration risk and supports steady growth.

3. Tracheostomy (selected cases)
   Why: Provide a stable airway and allow long-term ventilation/airway clearance when recurrent pneumonia or weak cough threatens breathing.

4. Orthopedic soft-tissue procedures (e.g., tendon lengthening)
   Why: Treat fixed contractures that cause pain, pressure sores, or hygiene problems; improves care and positioning.

5. Cardiac devices or advanced heart procedures (rare)
   Why: Pacemaker/ICD if significant rhythm problems; in exceptional cases, advanced heart-failure options may be discussed individually with cardiology given overall prognosis. NCBI

• New seizures or long seizures; back-to-back events; injury during a seizure.

• Swelling of legs/face, fast heartbeat at rest, or sudden weight gain—possible heart failure flare. NCBI

• Red eyes/eye pain, sudden loss of visual attention—possible eye inflammation or cataract issues.

• Any rapid change from the child’s usual baseline.

What to Eat” and “What to Avoid”

Eat/Use (as tolerated and cleared by the team):

1. Calorie-dense meals (add healthy oils/MCT per dietitian) to support growth.

2. Soft, moist textures or thickened liquids if swallow risk is present.

3. Lean proteins (fish, poultry, legumes) for immune and muscle support.

4. Fruits/vegetables for vitamins, fiber, and antioxidants.

5. Adequate fluids using oral rehydration solutions during illnesses.

Avoid/Limit:

1. High-sodium foods if heart failure is present (canned soups, salty snacks). NCBI
2. Unpasteurized dairy/undercooked meats or eggs (infection risk).
3. Hard, dry, or crumbly foods that are easy to aspirate if swallow is unsafe.
4. Sugary drinks that crowd out nutrition.
5. Excess supplements without lab-guided need (risk of toxicity).

Frequently Asked Questions

1. What exactly is Vici syndrome?
   A multisystem genetic condition from EPG5 mutations that block a key step in cellular recycling (autophagy), leading to problems in the brain, immune system, heart, eyes, and skin. GARD Information CenterPubMed

2. How is it diagnosed?
   Doctors look for the classic features (absent corpus callosum, cataracts, hypopigmentation, cardiomyopathy, immune dysfunction, developmental delay, microcephaly/failure to thrive) and confirm with genetic testing showing EPG5 mutations. Brain MRI and organ-system tests support the diagnosis. EyeWiki

3. Is it inherited?
   Yes. It follows autosomal recessive inheritance—each parent usually carries one silent variant; each pregnancy has a 25% chance to be affected. Genetic counseling helps families plan. GARD Information Center

4. Is there a cure?
   No curative treatment yet; care focuses on preventing infections, supporting the heart and lungs, safe feeding, vision/hearing care, and developmental comfort. Research on autophagy biology is active. PMC

5. What is the outlook?
   Severity varies. Many children have serious disease in early life; survival is often limited by infections or heart failure, though some live longer with specialized care. NCBIScienceDirect

6. Can immune problems be treated?
   Yes. IVIG and antimicrobial prophylaxis are commonly used to reduce infections; immunology follows labs to tailor therapy. PubMedOrpha.net
