[Disorders associated with alterations in single peroxisomal proteins, including X-linked adrenoleukodystrophy].

X-linked adrenoleukodystrophy is the prototype of the disorders that involve a single peroxisomal protein, and it is by far the most common peroxisomal disorder. The gene that is defective in this disorder is a peroxisomal membrane protein involved, in an as yet undefined manner, in the degradation of very long chain fatty acids. All of the peroxisomal disorders can be identified pre- and postnatally by non-invasive tests.
