Phytanic acid also accumulates in a number of other disorders with a very different clinical course: disorders of peroxisome biogenesis (Zellweger syndrome (OMIM 214100), neonatal adrenoleukodystrophy (OMIM 202370), infantile Refsum disease (OMIM 266510)) and rhizomelic chondrodysplasia punctata, type 1 (OMIM 215100). Phytanic acid is a 3-methyl fatty acid that cannot be beta-oxidized directly, and first undergoes an alpha-oxidation a reaction catalyzed by the enzyme phytanoyl-CoA hydroxylase, which is deficient in RD, the only true disorder of phytanic acid alpha-oxidation.
