A rare disorder characterized by phytanic acid accumulation in the blood and tissues.

Description

This rare disorder was the first example of an inherited disorder in fatty acid oxidation. It is characterized by phytanic acid accumulation in the blood and tissues.

The symptoms consist of night blindness (the earliest symptom), progressive nerve deafness, atypical retinitis pigmentosa, progressive concentric constriction of visual fields, lenticular opacity, peripheral polyneuropathy, absent or diminished deep tendon reflexes, cerebellar ataxia, loss of sense of smell, unsteady gait, loss of position sense, intention tremor, nystagmus, heart disease with ECG changes, ichtyosis, hyeprkeratosis palmaris et plantaris, epiphyseal dysplasia, syndactyly, hammer toe, pes cavus, urinary sphincter impairment, and osteochondritis.

Onset is in childhood or adolescence up to 30 years of age. The course is progressive, with periods of stagnation and partial remission.

Refsum, who observed it in five members of two unrelated Norwegian families, first reported the condition in 1945. His patients aged 25 to 41 years, were all born of consanguineous parents. The condition has since been observed in children. Inheritance is autosomal recessive.

This condition has been shown to be a disorder of lipid metabolism. In 1963 the German scientists E. Klenk and W. Kahlke detected large amounts of a peculiar branched-chain fatty acid, phytanic acid, in a Refsum patient. Dietary treatment started in Norway in 1966 under professor Lorentz Eldjarn (born 1920), Head of the Central Laboratory and Institute for Clinical Biochemistry at the Oslo University Hospital, Rikshospitalet.
