Phytanic acid storage disease, commonly known as Refsum disease, is a rare genetic disorder. It means the body can’t break down a certain type of fat called phytanic acid, leading it to build up in the brain and other tissues. Phytanic acid storage disease, or Refsum disease, is a genetic disorder where the body can’t process certain fats.
Types:
- Infantile Refsum Disease (IRD): A severe version affecting infants.
- Adult Refsum Disease (ARD): Milder form affecting adults.
Causes (Genetic Mutations linked to the disease):
- PEX1
- PEX6
- PEX10
- PEX12
- PEX13
- PEX14
- PEX16
- PEX19
- PEX2
- PEX3
- PEX5
- PHYH (or PAHX)
- PEX26
- PEX7
- AGPS
- FAR1
- GNPAT
- PEX11B
- PEX5L
- HACL1
(These are specific genes; mutations in these can lead to problems with peroxisome functions in the body, causing Refsum disease.)
Symptoms:
- Night blindness.
- Loss of smell (anosmia).
- Hearing loss.
- Weakness in limbs.
- Poor balance and coordination.
- Dry, scaly skin (ichthyosis).
- Numbness in limbs.
- Muscle pain or cramps.
- Enlarged liver.
- Heart arrhythmias.
- Short stature.
- Deformed bones.
- White dots in the eye (cataracts).
- Slow mental processes.
- Fatigue.
- Digestive issues.
- Thickened facial features.
- Speech difficulties.
- Difficulty swallowing.
- Spinal deformities.
Diagnostic Tests:
- Blood test (to measure phytanic acid).
- Genetic testing.
- Nerve conduction studies.
- Skin biopsy.
- Audiogram (hearing test).
- Electroretinogram (for vision).
- MRI of the brain.
- Plasma acylcarnitine profile.
- Electromyography (EMG).
- Electrocardiogram (ECG or EKG).
- Urine test (for phytanic acid).
- Funduscopy (eye exam).
- PEX enzyme analysis.
- Bone X-ray.
- Liver function tests.
- Spirometry (lung function).
- Smell test.
- Gait analysis.
- Visual field test.
- Skin lipid analysis.
Treatments:
- Dietary restrictions: Avoiding foods high in phytanic acid.
- Plasmapheresis: A process to remove phytanic acid from blood.
- Hearing aids for hearing loss.
- Physical therapy: For muscle weakness.
- Occupational therapy: To improve daily skills.
- Vitamin A supplements: If deficient.
- Speech therapy.
- Surgery: For skeletal deformities.
- Skin creams: For ichthyosis.
- Eye drops or surgery: For cataracts.
- Walking aids or braces: For balance issues.
- Pain relief medications.
- Supplemental oxygen: For respiratory issues.
- Pacemaker: For heart arrhythmias.
- Bone-strengthening drugs.
- Cochlear implants: For severe hearing loss.
- Eye glasses or contact lenses.
- Hormone therapy.
- Mental health counseling.
- Bone marrow transplant.
- Support groups.
- Regular monitoring and check-ups.
- Gene therapy: Experimental.
- Light therapy: For skin issues.
- Antioxidant supplements.
- Liver transplant: In severe cases.
- Educational interventions: For learning issues.
- Alternative therapies: Acupuncture, etc.
- Regular exercise: To improve muscle strength.
- Specialized schooling.
Drugs:
- Chenodeoxycholic acid: Reduces phytanic acid production.
- Lorenzo’s oil: Experimental treatment.
- Pain relievers: Like ibuprofen.
- Vitamin A supplements.
- Bone drugs: Like bisphosphonates.
- Blood pressure medications.

- Antioxidants: Like Vitamin E.
- Anti-anxiety medications.
- Hearing aid batteries.
- Eye drops: Lubricants.
- Anti-itch creams.
- Muscle relaxants.
- Sleep aids.
- Antidepressants.
- Antipsychotics: For behavioral issues.
