Refsum disease

Ref·sum dis·ease

(ref'sūm), [MIM*266500]

a rare degenerative disorder due to a deficiency of phytanic acid α-hydroxylase; clinically characterized by retinitis pigmentosa, ichthyosis, demyelinating polyneuropathy, deafness, and cerebellar signs; autosomal recessive inheritance caused by mutation in the gene encoding phytanoyl-CoA hydroxylase (PAHX or PHYH) on chromosome 10p. Infantile Refsum disease [MIM*266510] is an impaired peroxisomal function with accumulation of phytanic acid, pipecolic acid; autosomal recessive inheritance, caused by mutation in the PEX 1 gene on 7q.

Refsum disease

(rĕf′səm)

A rare autosomal recessive disorder in which an enzyme deficiency causes accumulation of phytanic acid in tissues, leading to retinitis pigmentosa, anosmia, and often ataxia, polyneuropathy, and other conditions.

The patient population consisted of the following: SLOS (OMIM 270400), 3 cases; CTX (OMIM 213700), 3 cases; sitosterolemia (OMIM 210250),1 case; and Refsum disease (OMIM 266500), 1 case.

Six samples were obtained from the follow-up during therapy of a patient with Refsum disease.

However, for Refsum disease, the total clinical picture is required because phytanic acid also accumulates in persons with Zellweger syndrome, neonatal adrenoleukodystrophy, infantile Refsum disease, and rhizomelic chondrodysplasia punctata type 1 (26).

As expected, the ratio for our Refsum disease patient was much lower (3.
