What is Refsum Disease?

What is Refsum Disease?

  • Refsum Disease: A metabolic disorder where a deficiency of phytanic acid alpha-hydroxylase results in a buildup of phytanic acid in the body which causes neurological disorders.
  • Refsum Disease: An autosomal recessive familial disorder that usually presents in childhood with POLYNEUROPATHY, sensorineural DEAFNESS; ICHTHYOSIS; ATAXIA; RETINITIS PIGMENTOSA; and cardiomyopathy. CEREBROSPINAL FLUID PROTEINS and serum PHYTANIC ACID are generally elevated. This condition is associated with the impaired metabolism of phytanic acid in PEROXISOMES. (From Joynt, Clinical Neurology, 1991, Ch37, p58-9; Rev Med Interne 1996;17(5):391-8)

Refsum Disease is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH). This means that Refsum Disease, or a subtype of Refsum Disease, affects less than 200,000 people in the US population.

Ophanet, a consortium of European partners, currently defines a condition rare when it affects 1 person per 2,000. They list Refsum Disease as a "rare disease".

However, treatment cannot undo the damage to vision and hearing. (Source: excerpt from NINDS Refsum Disease Information Page: NINDS)
