What is Refsum Disease?

Refsum disease is one of a family of genetic disorders known as the leukodystrophies in which, as a consequence of the disruption of lipid metabolism, the myelin sheath that insulates and protects the nerves of the brain fails to grow. It is inherited as an autosomal recessive trait.

As more information for our “Patient Perspective” section of  Refsum Disease becomes available, we will provide updates. Please refer to a Clinician’s Perspective for Refsum Syndrome.
