Adrenoleukodystrophy--a new mutation identified

Bratisl Lek Listy. 2007;108(10-11):462-6.


Introduction: X-linked adrenoleukodystrophy from the group of peroxisomal disorders presents with an extensive spectrum of phenotypes. The mutation affects the ABCD1 gene encoding a peroxisomal membrane protein. So far, its detailed function has not been clarified. However, it plays an essential role in the ethiopathogenesis of X-linked adrenoleukodystrophy. Its defect causes accumulation of the very long chain fatty acids in the tissues of the central and peripheral nervous system, adrenal glands and in the body fluids.

Purpose: To review the clinical presentations and diagnostic issues in X-adrenoleukodystrophy diagnosed in the one affected family.

Methods: A case report. Measurement of very long chain fatty acids. Molecular analysis of the adrenoleukodystrophy gene.

Results: A new "unique" mutation in the initiation codon in the first'exon of ABCD1 gene was identified. We present a phenotype description of a patient with this mutation.

Conclusions: X-linked adrenoleukodystrophy is a disease with the incidence rate approximately 1:16,800. Detection of new mutations contributes to better understanding of this rare disease and makes the diagnostic more available and precise. The importance of an adequate diagnosis is justified not only by a different therapeutic approach, but also by the need of prenatal diagnostics and the need of genetic counselling in the affected families. As demonstrated in our case, it is necessary to consider this diagnosis also in the adult age, e.g. within the differential diagnosis of spastic paraparesis (Tab. 1, Fig. 4, Ref 23).
